Stimulant, dexedrine is what worked for me. At one point I tried a number others and they didn't seem to work the same, even Adderall wasn't the same but I know it's very similar. Know Vyvanse was another, but know there were a couple other I don't recall. First one was Ritilan but that gave me hives which took me a bit to register why they were happening, well two days but easy enough since it was the new thing.
