You said you were feeling like shit, can you describe the symptoms?
Honestly, all started a few months back, when for whatever reason I decided to go on a cleanse and eat only salads / veggie stir frys. Every two or three days I'd allow myself to throw in some shrimp or fish, to get a bit of protein.
After a couple weeks of that, I ended up quite fatigued, and literally slept 16 - 20 hours a day for 5 - 10 days at a time. I just couldn't keep myself awake. I'd wake up, have a strong coffee, and it wouldn't matter -- an hour or two later I'd find myself laying in bed watching a movie, and next thing I knew it was 10 hours later. Then I'd be good for a few days, and then back to sleeping for a week.
The fatigue seems to have disappeared for whatever reason, as I can keep myself awake for a decent while now. For the past week though my hands, feet, and lips have been numb and tingly. Not painful or anything, but numb. Also can't sleep anymore for some reason. Get a couple hours at a time, about 3 times a day, hence why I'm probably going a bit goofy right now -- my body is hurting for some quality REM sleep.
After reading up, I'm sure it's diabetes. It's in my family, and the symptoms match up. I don't care in the slightest that I have it, but will be nice to have it taken care of. I know full well I'm getting it, so get it now or in a decade from now -- doesn't matter, I'm still going to get it.
I'm just curious as to what is feels like to get those first shots of insulin. I mean, diabetes means your body isn't capable of storing and processing cells properly for energy, so what happens when the insulin gets introduced to your system, and those functions begin working? Do you just start feeling fine again, or is it more of a "holy shit! I totally forgot it was possible to feel this good!" type of feeling?
