Grats... i've started and quit more times than I would like to admit... everytime I get stressed out.. that's what i turn to. That's awesome that you stuck it out. Hopefully someday I will be able to as well.
You get shaky, sweaty, lightheaded. I use to stay on the ground more than my feet. If you are thirsty alot or go to the bathroom alot at night, all are symptoms. Even if it is hypoglecmia, you need to know how to eat. Good luck and please be checked out. I now have neorapathy in my left leg and have had heart problems because of it. It sneaks up on you.
