Long story short I had abused caffeine and stims for a long time. Suffered from adrenl fatigue. Something like 10 years now. So I recently started cutting back. After last week when I drank an amped and felt like I wanted to sleep. Got my head kicked in for 15 rounds. So curious what you guys use pre workout before training sessions. I'm done with caffeine and shit. Got to the point that 3 big redbulls a day and I was tired.
