I've already done it, but a question on how much to take for the next time

I did 90mg of adderall xr swallowed about 2 weeks ago and it was soooo good. Stayed up all night and felt absolutly fantastic, really really hyper and interested in pretty much everything. That was at 11pm on a saturday. The night before I only got about 3 hrs of sleep, so out of 54 hrs I only slept for 3.

When I crashed and was tired I slept for about 14. So that monday I got the craving to do it again. I wanted to conserve pills so I just took 60mg. It did hardly anything. No euphoric feeling, not even feeling really focused compared to the first time. It did keep me up a bit and sleeping that night was tough, but I also got totally smashed mid day (this was st. patricks day). So needless to say I was dissapointed with the effects of adderall that time. I tell my self it was to close to the first time and let some days go by, 11 days in fact and do 60mg again.

This time I get a bit more hyper and I pound out a school project. I did feel kinda focused. The problem is I didn't get that "great this is fucking awesome" feeling. Had trouble sleeping that night too, probably only slept for 2 hrs. So the second and third times were pretty much nothing special. That first time was uncomparable. Literally the best time I have every had on a drug and I'm just trying to get back there. Say I were to do it again friday, how many mgs would I have to take? I know the answer is going to be over 60mg.
