This thread makes very interesting reading. I guess caffeine is okay so long as you remember to drink lots of water as well.

As an aside, I was on semi-detox for the whole of July. I say 'semi' as around the 21st July I was with my parents and suspect my decaf coffee was mixed up with their normal coffee. Wow, after 3 weeks of no stimulants I was high as a kite for an hour and then was nauseus changing to lethargic for the next 1.5 hours.

Having said all that, I'm about to go out and buy some Xenedrine to aid my August "High Protein, Low Carbs, High Fat Loss Campaign" - guess I'll be on 1 tab a day before my morning jog!!
