Last week I decided to try some AMP. I took the recommended dose and I didn't feel any effects at first. Then about 30 mins-45 mins later I started feeling really groggy and had an almost a euphoric feeling. I didn't get any energy at all whatsoever, and I actually felt kind of tired. When I went to workout I felt almost sluggish. My diet was normal that day, and I wasn't going hypo or anything. I tried it again yesterday, and received the same effects. No energy, just a weird sluggish, happy feeling. Can anyone explain this?
