Hi there ~
I understand your concerns. The abuse of meth
has caused you to have dependence on the substance to the point where leaving the medication for even a few hours is causing you to have withdrawal reactions from the medications. I believe that you are having shooting body pains and rashes due to the same reason. You might have to consult a psychiatrist
who is experienced in substance use disorders to have your condition treated. I advise you to take no medications till you visit with and consult a psychiatrist.
I hope this helps. Take care and have a lovely day!
