extended high dose adderall use

[dualityno31]

As of late swim has been very lazy in college, mostly due to excessive marijuana usage. Now swim is trying to catch up and found a connect to adderall to help swim study. Swim has tried it a few times before, but since Sunday afternoon (its now Wednesday) swim has somehow taken 300 mg in the form of several extended release gelcaps. The first 2 days were productive as well as euphoric, but Tuesday rolls around and the boosters don't really provide any more euphoria, just stimulation. Swim has lots of work to do and of course will not do this again for a while, but what swim wants to know is how bad for you is it to ingest 300 mg over a 4 day period, and why is it that the high went from being incredibly euphoric everytime he popped (about 75 mg thoughout a day) to just stimulation. Is it possible to already to have built that sort of tolerance in just 4 days? Also, I have had mild hallucinations since Tuesday and actually its been sort of neat, but wanted to know if thats normal after just a 4 day binge.

Thanks for any response
