Nats advice sounds like a must do. Also, I had anxiety attack experiences when I tried a low carb program in the past. I found out that I am sensitive to coffee and that once I stopped the high carb lifestyle I could not tolerate it at all. It made me batty (and made my insulin spike)!! I stopped the caffeine, went through withdrawl (not fun), and now I am doing pretty good on this thing. Some people are just really drug sensitive and can't take stimulants. I hope you find what is causing you so much discomfort. Good luck!
