Wellbutrin and ears ring

originally was taking 150 mg and after a few days increased to 150 mg 2x/day. Those first couple of days taking two a day made my ears ring LOUD! And I had rather extreme bout of depression, more than I'd ever experienced with uncontrollable crying and wanting to die.

Lack of appetite, very dry mouth, constipation also present.

Doctor suggested 150mg sustained release and most side-effects gone except for inability to sleep.

probably going off of it because I hate taking any kind-of drug and certainly don't want to endure any long-term side-effects.
