Anxiety
"I have been taking Atenolol (50mg) for a month or so now. There was an immediate drop in blood pressure and my anxiety has lessened so that I need my Xanax much less often.  One thing I have noticed is that I wake up a few times a night with pain in whatever shoulder I have been sleeping on.  It feels like joint pain and lasts for about an hour after awakening.  Otherwise it does not effect my sleep. Another side effect is that, an hour after taking it, I yawn and my eyes water.  Also, the first two weeks I took it I had diarrhea when previous to that I was constipated, but that has subsided."
