I am on 4th day Wellbutrin SR 100mg, once a day. I know that’s a mild dose, but so far I have no effects, good or bad. Well on day to 2 felt unsusually fatigued, but that’s it.

In the past years I was on Wellbutrin XL 150mg and 300mg for a short time. The effects were noticeable. I was energetic, lost appetite, and became severely constipated. Which is why I stopped taking it. However, nothing this time.

The main purpose I was put on Wellbutrin was to control or lose weight.

How long should I wait before seeing a change? Any change.
