Was a 400+ carb/day junky, would eat half a loaf of bread occassionally toasted with margarine on it, taco bell, mcdonalds, etc,etc. drank only mountain dews up to about a month ago but would still drink a lot of dews up to starting atkins

Ok, been holding to atkins good since sunday morning, taking vitamins, drinking 100+ ozs water/day, ketostix show moderate ketosis since tuesday etc....

The one person I know personally who has tried atkins felt like crap the first 5 or so days. Other people on this forum have commented that they feel/felt like crap for the first few days up to a week or two.

Question is, am i doing something wrong that i don't feel like crap and haven't since starting? Not really felt at all bad since starting. Or are others of you like this that you didn't feel bad when you started?
