Robibaby, I totally agree with lessthan. If you're depressed and eating out of control, you'll do more damage (gaining weight) than being on the Wellbutrin alone.
Also, your weight isn't your life. Think about DH and baby and kids, they need their mom to be in control and depressed isn't being in control.
BTW, I understand the not wanting to take meds, I did quit cold turky 7 months ago - BUT - my symptoms are for the moment not bad. I would go back on them if I needed to.
Good luck!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! And congrats on the baby.
