I have had type was for 23 years. Besides when i was diagnosed (BS was 1150! They said i should not have been conscious.), highest recorded is just HIGH, which I think means over 600? Anyway its bad. Lowest is around 43, BUT I did pass out for my first time this past year when I was adjusting to being on the pump. I was fortunate, i was right next to my bed when it started crashing and somehow i knew it was a bad one, I quickly crawled across my bed and opened my glucose tabs and then....passed out in them. I am very grateful nothing like this has ever happened to me before. I am also grateful I was not driving or out in public somehow. Instead, I just remember eventually sorta being in this pink cloud. I felt great, everything was great, just perfect. I remember thinking, oh I could stay here forever. .....wait.....where is "here"?......wait, was I suppose to be doing something?....etc etc....it seemed like it took a long time to remember what was going on. I woke up soooooo gradual and eventually found myself in my glucose tabs and got one in my mouth finally, and it continued to be gradual, i was in fact pretty tired and low key for awhile after it happened. It was also in the evening already so the whole incident just wiped me out for the night. My dog and at least 2 of my cats were also on the bed and as far as I can tell, they didn't notice anything was wrong with me at all!!
