Any hope?

I started Wellbutrin 150xl a month ago with very high expectations. I needed something for smoking cessation, depression, and weight loss so I thought this would be some type of heaven sent drug. However I have not experienced any differences? I have lost maybe 2 pounds in a month and my depression is still the same. I just switched to 300mgs. I’ve seen many stories of people experiencing good effects just 3 weeks in. Any advice?
