started doing dexamfetamine to work on an assignment a couple weeks ago. i was taking 5mg a day in 2.5 doses (i'm 4'9 and about 40kg with no tolerance), was working for a few days, had a freakout while it was wearing off due to external circumstances that ended up lasting a week and then started again to try and get it in by the deadline on the 27th. i never took more than 5mg in a day but i'd still feel some effects on my heart, couldn't go up staircases and stuff while i was on it cuz it'd go crazy. on the day it was due i kept dosing every 2 hours or so to try to avoid it wearing off and getting confused, eventually i did get confused and couldn't get out of it so started increasing the dose frequency to an hour and a half, an hour, 45 mins. at some point when i'd get out of bed to take more my heart would go crazy, blurry vision dizziness and chest pain and i'd still go to take more. needless to say my essay did not get finished and my heart has been feeling pretty bad since, but my friends are saying it's just the continued stress. to be fair i have been extremely stressed. I took about 50 mg over the course of about 27 hours which isn't technically a lot. i slept well the past 2 nights and i'm still kind of getting chest pain. the day after my blood was rushing so loud in my ears i was getting actual tinnitus and i've been having weakness in my arms and hands. will this pass or did i fuck something up?? it is feeling less crazy today but i still do get mild chest pain and can hear my blood rushing in my ears occasionally.
edit: i forgot to add that i was kind of delirious that day after i stopped dosing (essay was due 4pm). i was really confused and strange and experiencing weird physical symptoms, my friend that came to help me was confused. but we chalked it up to lack of sleep.
