I was put on 50mg a day of Atenolol when first diagnosed a hypertensive. It was hell for me. Then got dosage reduced to 25mg when my BP came down a bit. That was a little better. Finally, I could'nt hack them anymore and was put on Micardis which was much less in the way of side-effects. I can't imagine what it's like on 200mg. Glad to hear your dosage was reduced.
