I do very low carb, I'd say 5-7 days of the week I do zero carb (except for cream in my coffee, and a glass of white wine). I find I'm never hungry, can go almost the entire day without eating, but usually throw down some protein just because I feel I should. I throw in some veggies the other 2 days to keep my bowels moving.
I wake up with a headache every day, so vlc isn't what does that. I never feel nauseous, as a matter of fact, I feel great. I do get cotton mouth ALOT. I have to have water by my side 24/7.
