Hi, this is my first time on here so tell me if I'm doing something wrong. A while back I got prescribed Adderall, I'm 18 and have had add/serious problems focusing for ages now. He has been slowly increasing the dosage over time, I now take 15mg ir at 9am and 1pm. I feel NOTHING, my heart beat gets a bit faster but other than that, nothing happens mentaly, I do have a slight comedown later on . I also take Wellbutrin xr 300mg in the morning and seroquil 125mg and lamictol 200mg at night. I read online that seroquil can counter the effects of adderall (mine is taken at night so not sure how it would) so I decided to one morning try 30mg it at once in the morning, 1.5hrs later still nothing. That night I didn't take my seroquil just to see if that was the issue. The next day at 9 I took 30mg, 1hr later and nothing (on a near empty stomach with no fruit or acids) so I took 30 more. 1hr later and nothing... I finally took another 15 and decided to stop at that. 1hr later and my heart was pounding, but I felt NO OTHER CHANGE, about 4 hrs after my last dose I started to crash hard, got super sweaty, light headed, and felt cold and depressed, I decided to take a shower and go to sleep and since then I've been back on my normal prescribed dosages of all meds... I don't know why it's not doing anything for me, any help? Thank you!
