Besides which, you may find your tastes changing as you get past the first week or two and you might actually LIKE veggies.

This weakness is part of the carb withdrawal but there's no need to feel HORRIBLE. As was said above, eat some extra salad - it's hard to overdose on lettuce or cucumbers. ANd buy some "No Salt" salt substitute to give yourself some extra potassium for the fatigue.

If you did cut out caffeine completely, have a cup in the AM to get yourself steadied. But begin to mix in some decaf and gradually cut down over the weeks.

Sorry you are feeling depressed but this weakness is NOT failure - it's normal and we all went through it. My DH has high BP & takes meds for it. When he started, he got dizzy & weak because the diuretic effect of the diet plus his meds lowered his BP TOO much. Food is powerful stuff. And you CAN win.

Day 3-5 is the worst after that, things get much better AND you lose pounds.
