Hi Tryin
By reactions do you mean side effects?
If so, I was put on 300 meg Wellbutrin ER about 6 months ago. The side effects (for me) were horrendous!! I wanted to go off, but pdoc (and encouragement from this site) convinced me to wait out the side effects. They were: extreme fine and tremors to the point I couldn't write; loss of balance (I was put on driving restrictions during that time); knew what I wanted to say in my head, but couldn't get them out of my mouth; felt like I looked like I had had a stroke; would stare at my money when paying for something and tried to think of what denomination each bill was; and finally, weird feelings in my head. They lasted for approximately a month then went away, except for some fine hand tremors now and then.
Now I am being weaned off Wellbutrin with 150 mg XL. I had some side effects when I first began it (but that is coming OFF Wellbutrin) but not as severe. Main side effects this time were - excessive sweating; being hot, then cold, then hot, etc.; hand tremors back again, flu-like feelings. I only had them in the morning and by late afternoon felt well again.
Now I'm not experiencing any of them.
Hope it goes well for you...I have no info on Lopressor.
