muscle spasm
"I have been having odd neck and shoulder problems for a while. My doctor seems clueless as to what the issue actually is.  About a week ago I woke up them a lot worse than usual and it felt as if my shoulders had fallen asleep. Called the doctor saying this can't be normal. Went to see that doctor. Who looked stuff up on some badly done metric. Only took two of the tablets.  Feeling strange - and not at all myself. This is a very common effect of this stuff. Who ever approved and suggested turning off a bunch of random switches needs their heads examined. And this stuff needs to be taken off the market as mostly junk. Just junk. For me it feels toxic and weird and not at all myself. That is not ok."
