Take a deep breath. You aren't going to die in your sleep becuase of a low. My days are similar to yours. Sometimes i'm at a desk sometimes i'm on my feet, and somedays, I have no idea which one it'll be.Here are a few suggestions:
-Have a snack with you that you know will work to raise your Blood sugar quickly. For small and quick things, I use Wurther Butterscotch candy. I know exxactly how much it'll raise my sugars and it's pretty consistent. Try to find a quick and handy snack like that for yourself. The smaller and easier to pop in your mouth and forget, the better.
-I also usually have a slower acting snack that I know will take longer to raise my BS but will be more even out and not a quick spike like the Wurther's candy. I use Nature Valley Protein Chewy Bars (Peanut, Almond and Dark Chocolate). with 14g carbs, I know this won't spike me, but gradually raise my BS so when I know that I'm going low, and think a spike willbe too much, and when I know I'll have a few minutes to sit and eat it, I'll have the bar instead.
-A few folks above suggested getting a CGM. I can't recommend that enough. I got on one recently, and to be honest, I don't know why this isn't standard issue for anyone diagnosed diabetic. Particularly type 1 or 1.5. It opens your eyes and helps you prevent highs and lows rather than wait for them too happen. After getting my Dexcom (the one I use) i felt like having it was akin to walking a cave with a flashlight and headlamp whereas the before having it experience now felt like i was trying to use a cell phone screen to get through the cave. I could now see where my BS was going rather than waiting for it to happen. I tested and test BS often, but still, I felt having the CGm was a huge improvement and help in getting me data that I could use to take better care.
- I recently began using an insulin pump. I have to say that it has improved my care greatly. i could fine tune, like i never could on dadily injections. I was doing 10-15 injections to stay on top of things, but still, it has been much easier with the pump. one of the reasons is that on my pump (Animas Ping) you can set a several different basals basoed on hours ( I use 5 different basals for different times of the day). Also, You can increase or lower your basal by percentage for even more tweaking on the fly. You can do this based on half hour increments. So you can say drop your basal by 10% for half hour or four hours or go up 20% for 3 1/2 hours if you need to.
It sounds like this kind of thing would be very helpful to you as your day seems a bit different on daily basis as mine is. Feel free to send me questions if you like. I know what you are going through. I think many, if not all of us on here, have the same fear. Take a deep breath. Relax. Everyday is a learning process with diabetes. No two days are different and sometimes things just go crazy for no apparent reason. it's important to take it a day at a time, and sometimes a moment at a time, not burn yourself out with stress. Somedays, you'll do your best and it'll work out great, your numbers will be awesome. Other days, you'll do the exact same as before and it'll seem your numbers are terrible. Don't burn yourself out. Just take it as it comes and do your best. That's all that any of us can do. And also, know you aren't alone, though it sure feels like it sometimes. So go dance, hang out and live and enjoy. Just have the stuff you need with you in case you go high or low. Be prepared for the possible diabetes situations and you'll be fine. :) Anxiety comes with wanting to be in control all the time. Sometimes, that's not possible. You just need to know that you can always bring it back in control, but sometimes, it'll get out of control on its own. it just is what it is. you deserve a happy and healthy life, you just need a few more tools than most people cause your pancrease, like mine has, decided to go haywire on it's own. No matter, you can still have a great time without it. You just have to do the work it would've done for you m, mannually. :) Smile! Your job and friends sound like a blast.
Oh, one more thing, telling folks about what a low may cause for you and how to help you out of it, is important in case you ever do go so low that you can't help yourself. I read a book called Not Dead Yet (Phil Southerland), that recommends telling 7 of your closest family,friends and/or colleagues, folks you feel comfortable with and close enough to, let them know that you have diabetes and that if you ever went extremely high, or extremely low, this is what they should do. If you carry a glucogon pen, tell them how to use it. if you or they aren't comfortable with that, then instruct them to call 911 immediately for you. whatever you are comfortable with, but tell them what may happen if you go low and what to do about it. As it seems your fear is of having this happen to you when no one is around (during the night) maybe you want to tell your closest relative or best friend to check on you daily, or until you feel more comfortable in handling things, with a simple text or call in the morning and what steps to follow if you don't respond or can't. Anyway, Didn't mean to go on forever, but I hope this gives you some food for thought. Again, let me know if you'd like to talk about it more. By the way, I've set these up myself for the same reasons you are asking. :)
