Hi there ~
I understand your concerns. I understand that you are aware of the side of the methamphetamine
abuse. The strange effects are the result of your withdrawal from methamphetamine. I believe they will eventually go away however you need to consult a psychiatrist
to get symptomatic treatment for the withdrawal reactions that you are experiencing from going off of the methamphetamine. You may also do well with getting an MRI
of your brain to rule out any abnormalities.
I hope this helps. Take care and have a lovely day!
