High Blood Pressure
"For 7 years I have been on 50 mg. of atenolol for hypertension.  Most of my nights I have had wakeful periods and generally non-restorative sleep.  I asked to try Tenormin instead of the generic and found the opposite - sleeping in and needing afternoon naps.  For the past few weeks I have been on 25 mg. of the generic and 25 mg. of Tenormin and this seems to be a good balance. Supposedly these two drugs are the same but something has made a real difference for me. in so far as sleep quality is concerned."
