So I just got an order of Artvigil 150mg to try and help me with studying and school work before finals. I have practically no experience with nootropics or anything of the sort, but I was surprised by the lack of effects it had. I know its not a stimulant like adderal, but I honestly felt next to nothing from it, I was still tired throughout the day and wasn't really able to work for long stretches of time. For clarification, I've taken it multiple times, the two most recent ones day after day on an empty stomach, but I felt no difference. Is there anything that could be decreasing the effects for me, like sleep or diet, or maybe other supplements or drugs I'm on?
