Dear Welcome to HCM We understand your concerns I went through your details. Crystal Meth addiction is all too common around the globe. Due to the excess adrenaline produced by crystal meth, many individuals experience repetitive motions. Users may experience involuntary muscle movements, muscle twitches or hand wringing as their bodies respond to excess energy. This drug may also cause the following symptoms that are related to muscle twitching: Damage to nerve/brain cells Motor tics Phonic tics Tics/jerking movements Tourette’s syndrome Worsening of tics The above issues are also to be investigated for. The best method of treatment would be to consult a de-addiction therapist and get medicines. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
