I Was On Heritage Brand Propanolol For 6 Yrs. Slowly

I was on heritage brand propanolol for 6 yrs. slowly moved up to 20 mg 4xs a day. They stopped making. Oct 2015 went to Milan, felt very off tried for 1 week.. Went to Watson 30 mg a day and clonodine patch. Reaction to adhesive of patch. Went off patch Friday., Dr moved dosage from 30 mg a week to 40 for 1 week then started 80 on Monday.. Feel off. Feel drugged. Ugly taste also. Now going to try different generic Qualitest tomorrow. Why am I having such a hard time with generics of propanolol? I had no side effects on heritage all those years. I am taking for high blood pressure also cuts down on anxiety. Druggist thinks may be absorption as he looks out of side of eye? My Dr does not feel it's the drugs but me. I do not agree.
