... take action. I asked for Wellbutrin, because I had been on Zoloft for PPD after my second child and felt it didn't really help. I wanted to try something other than an ssri. I did feel like the Wellbutrin 150 XL was helping, but it caused insomnia. I would wake up at 5am every morning and couldn't fall back asleep. I wasn't ready to give up on Wellbutrin just yet and asked my doctor for Wellbutrin SR wondering if maybe a different way to take it might help. It has not. If anything I've gotten more side effects, like the jitters and my stomach flipping for unnecessary reasons like I'm worried about something. Is this even possible? I'm taking the same medication. Same dose. Why would I suddenly be feeling worse?
