I know what your talking about. I get hungry around 8pm every night. I can kick ass on the diet all day, but its around 8pm that the craving starts. Im totally cutting carbs, so its really tuff... everything has carbs!
Then, every diet pill out there will keep you awake all night, so its not like you can take anything....
I have learned that if i take a diet pill around 6pm ill be wired, but no cravings. Its been worst for me though cause im trying to use the diet pills less now... and work on the willpower more. But i've screwed up a lot. Just last night i couldnt resist a cupcake that we had out for my daughters birthday.... son of a bitch!! -lol!!
