I'm on day 6 and I feel terrible. I went on it for the usuall 11 days once berfore and I felt terrible then also. Every time I try to go for a run Afterwards I feel like I'm going to pass out on the road and I can't even walk straight. Went through the same thing last time. It didn't just pass last time and I doubt it will this time either. I need the quick weight loss so I just put up with it cause I need to go to basic training and I'm to heavy to go. So much for feeling healthier and refreshed. I don't feel like that at all and didn't feel like that last time either. I feel deceived.
