So I (21F) have known most of my life prior to diagnosis that I was Bipolar. I got diagnosed at 18 w/Bipolar type one and MDD. They gave me Seroquel (Quetiapine) and Wellbutrin XL (Buproprion XL). The combination seemed to work well except for the Seroquel side effects. It would cause extreme thirst. Sleep eating. Eating everything in sight after taking it. And I've noticed it's trashed my short term memory. But its allegedly the best for bipolar type one. Especially for breastfeeding moms, which I am. My question is- Are there any good alternatives with less side affects? Is there anything that's not gonna make me gain a lot of weight or eat a lot before bed? And can these alternatives be safely taken with Wellbutrin XL. Because Wellbutrin works well for my depression but without a mood stabilizer/antipsychotic it makes me MANIC. I took it alone for PPD. A little side note: I've only ever been on this combination before and I like the way it helps keep me calm and collected but I don't like what it does to me physically. Am I just SOL or are there alternatives? 

TL;DR: What alternatives(if any) to Seroquel/Quetiapine have less side effects and can be paired with Wellbutrin XL?
