Chillin408, no it doesn't affect me that way. But, it appears to be stronger to me than Hydroxycut at full dosage. Providian, you're right about trouble sleeping. I took it one time around six before I lifted and couldn't sleep at all later on. So now I'm going to stick with taking it early in the day. Seems like one helluva diuretic too, as it seems to strip the water from your body.
