two months ago i accidentally took a 300mg dose of meth thinking it was mdma, and havent touched amphetamines since. from the research I've done I have convinced myself I am now permanently fried. I know it is meth because I did a mecke reagent test on some that I bought from the same source, which looked exactly the same, and it turned orange immediately. can anyone offer insight into how badly I have damaged my neurotransmitters? have I done extensive brain damage or can my body heal for the most part? I'm not looking for a sugar coated response, but I am very stressed thinking about it so any information will help me reconcile this experience.
