Hi....sorry you're having so much trouble

You're right in the thick of carb and caffeine withdrawal and these symptoms should dissipate in a couple of days. A couple of suggestions for you: instead of withdrawing "cold turkey" on the caffeine, try weaning yourself off over a few days or weeks. Make sure you're drinking your water, 64 oz minimum . Be faithful in taking your vitamins: a good multivitamin, a calcium-magnesium supplement and 400mg of potassium every day. (Note: do not supplement w/ potassium if you're taking meds for the treatment of high blood pressure.) Oh, and do make sure you're getting adequate calories.... no fewer than ~1350 for sure!

Hang in there...this is tough to go through....but it'll be over soon and you'll be feeling like a brand new person!
