I take medicine due for my heart problem carrying 3 stents. For quite sometime during sex, my pennis for short time erects but then it calms down. Making much efforts doesn't help me. I take embeta r mg medicine, daily one tablet. I am erected to smoking, drinking. I have no control on me. I think too much also & find small reasons for quarrels. Later I am cool. This is my big weakness. Eyes also burn, feel drowsiness during the day. Please advise. Please guide me.
