REGARDING DIET PILLS I've tried some containing ephedra. First off, the effects are VERY marginal as in a 1-3% metabolism increase. Most of them are very strong as in coffee x 20. So you'll be very much hyper, upside is that you'll get alot of your stuff done really quick (studies/work/workout). Even Downside, heart palpitations. You'll be very tired next day. If you have any congenital heart defects these pills can be somewhat hazardous to your health. Summary: Energy boost, not a fatburner. I wouldn't recommend taking every day either as it can lead to complications.
