for whatever reason, modafinil is basically a sugar pill for me. Armodafinil at full dose (150mg vs 200mg for Moda) will keep me going strong for around 36hrs before I start to fade. I was down to quarter tabs daily so I could still eat like I actually wanted to train like an athlete. I would eat sub 1k cals a day on a full tab and be fine with a refeed every 3-5 days as long as I hydrate enough throughout. amazing for cutting, gaming, work (my work is a lot like gaming), and shit for spiking anxiety. however I was using it in a really stressful period of life so that could have been a factor.
