Cooperation symptoms and conditions

Started on Metoprolol about two months ago for a sudden onset of heart irregularity, mostly skipped beats. I'm already experiencing some of same problems described on this site. Because of that, I was looking for information and ended up on this site. My symptoms include daily headaches, inertia and lack of motivation, feel like sleeping all day long, wt gain, foggy headed, bloating and stomach discomfort. These symptoms have either started or intensified since I started on this medication. I plan to wean off this as soon as possible, with or without the doctor's cooperation. I've had a cardiac workup since I started the medication and no problems were detected.

I wanted to know the Long term side effects or irreversible side effects?

Thankyou for your cooperation in this matter.

Sincerely,

I have a sister who is mentally retarded and they want to give this to her for behaviors - I say NO she has seisures, too. There are too many side effects on this medication.
