I had the same thing. The first week felt like Adderall with better focus and drive to get stuff done. Now I only get brief flashes of it a day or two after injecting, but nothing like before. Still at 1 mg at the end of week three and thinking about going up next time.
Anyone notice the strong energy lift from the first week on reta disappearing after that? Mine felt like a couple of coffees, giving a nice spring in my step without being jittery. It faded after week one and I miss the extra zip. Started at 0.5 mg for a couple weeks, moved to 1 mg, then 2 mg, and eventually reached 4 mg before dropping back for other reasons. Raising the dose to chase the feeling again would suppress appetite too hard.
