Hi there ~
I understand your concerns. Using methamphetamine for a prolonged period of time will make you dependent on the drug both physiologically and psychologically. I believe that you may be having these symptoms of tingly feelings and numbness as well as dizziness
due to the same reason. I advise you to consult a psychiatrist
who is well versed in treating substance dependent patients to get help with detox. You may also need hospitalization and rehabilitation
for methamphetamine dependence
I hope this helps. Take care and have a lovely day!
