I recently replied to a post about eating too much sweets when they knew they did not need them. I just really wanted to record this for my own records because I made me feel good to see this written.
I was on this roller coaster for the longest time. There are a couple things that got me out of it (or at least I attribute to correcting the problem).
1. Don't get into the habit of correcting low sugar with something you secretly want to eat a ton of. Use those glucose tablets. I was always in the mind set of "why eat some sugar I don't really want when I can just eat ice cream". This usually causes you to eat too much sugar. Definitely avoid carbohydrates to solve sugar issues (always use simple sugars). They won't bring your low up quick enough and you will definitely end up eating too much.
2. If you use a pump, perhaps you parameters are out of whack. I was in a really situation for a while because I would over bolus, over eat (because I was sooo sooo low), over bolus, over eat pee pee pee pee, never ever sleep.
3. And this is the dangerous one. Be comfortable with lower blood sugar. Background, I went to work in Norway, I was sooo excited. But they require very low HbA1C to work there. When my chance to stay working there was threatened by this, I went on diabetes lock down. I tried to push my limits on comfort with lows more and more. I monitored 10-20 times a day. I would get ridiculously meticulous about the bolus wizard on my pump. The result. When originally I thought my genetics made me more comfortable at 150-210, I was wrong, it was just my body was so used to higher numbers. Now I am normal feeling at 60-80. Now you ask. Why is this useful? Well, if you feel low and your normal feeling is high you have a tendency to eat a lot. If your normal is lower, you will have a tendency to need very little sugar to get back to normal feeling.
The last one you really have to be weary with. It takes time and work to get comfortable lower. But it drastically changes HbA1c and average mg/l and it generally makes you healthier and easier to control.
