i am just starting week 6 and during the day i feel absolutely fine and i am on the go all day. i do feel more tired in the evenings - by about 9 oclock i have had it and just need to veg out. i try to slow down a little by early evening and dont over do it. i think everyones side effects are different and im just taking it one day at a time. i must admit that the weight loss more than makes up for the fact that im a little more tired in the evenings. i do hope your side effects clear up quickly and wish you luck with the next week. x
