I started taking wellbutrin xl (bupropion XL) 150mg about a week ago and I haven't noticed any change in my mood other then I'm not really sleeping. I've maybe slept 20 hours in the last 7 days. I have crazy amounts of energy but I'm still depressed and my anxiety is still through the roof.

How long on average does it take to see improvements with depression?

Is it true it will help me lose the weight I gained while my depression was untreated?

Do I need to quite smoking right away? How does it help you quite smoking?

Thanks in advance
