On the past two weeks I have been obtaining meth that really had no effect like I wanted it to and my muscles would be sore,I would twitch, general lack if focus on anything, spitting up phlegm, and a knot if anxiety in th canter if my chest.Alsp one minute i wm reading and then not there mentally. .nodding off. I am afraid one day that I will forget to put my van into park and nod off causing more anxiety., Last night I tried it again and was nauseous all day. Please how can I figure out what it is. I am not doing any more but I am still nodding off.
