Dear mismis ~ It almost sounds like you are having med side effects, but I don't think Celexa causes anything like that - or Xanax for that matter. You should probably report these feelings in you head and teeth to you MD and pdoc both. I know that I grind my teeth, and I worry that it is a side effect of Reglan, which I take for esophageal spasms. So it's hard to say. Also, I have read, and experienced, electric feels going through my head, when I was withdrawing from Cymbalta. Hopefully, you will discover the cause of this and/or it was pass. I know the feeling of being so unmotivated. I tend to stay in bed at least every other day and to shower only when I have to go out. Thankfully, I do have to go out for various things! Praying for you ~ billieJ
