high blood pressure
"I'm on 150mg Atenolol, I take 100mg in the morning and 50mg at night.

Side effects are, leg water retention, breathlessness on exertion due to too slow heart rate, breathlessness when sleeping due to even slower heart rate, this in addition to dizzyness.

I should mention I sauffer from Diabetes type 2, insulin/diet controlled, so there may be an Insulin/Atenolol conflict there, and polyneuropathy to the extent I can no longer walk as my legs no longer respond to instructions from my brain."
