Bell ringing symptoms and conditions

I have been on Wellbutrin SR for 1 year now. 100mg once in the morning. Have had 18-20 lb. weight gain, more anxiety(take alprazolam at night to help me sleep due to anxiety).I also at times hear a faint "door bell ringing" and am very short tempered towards my family.. Massive insomnia. I am trying to wean off and start over, but am experiencing major heart palpitations/anxiety along with alot more sleep issues. I don't know if my weight gain if from wellbutrin or alprazolam? My doctor said it was neither and it was because i'm in my 40's now. Wrong!!!!!!!!!!!!! Something is not right.

my side effects are blurred vision,fatigue, emotional,not with it, extreme palpitations, anxiety, shortness of breath, and high blood pressure.

im into my 1st month and everything is going good. after reading all these postings im wondering if i really need it. until now i never realized how crazy everyone sounds, seeing double, gagging, weight gain, body shakes,door bell ringing in your ears on tuesdays,. what next? you'll see a UFO? come on people....... what you need is a drink.
