Does Anyone Else Take Lithium?

I'm about 6 weeks post now, losing nothing. Had 1 fill so far and going for another next week (although I'm really not sure I need one, I don't have any type of hunger that I can't deal with).

I'm watching Protein (at least 60g) and carbs (around 50g) each day, not snacking and definitely finding it hard to get more than 600-700 calder unless I'm eating junk between meals. I know this could be a problem but..

I also take lithium for bipolar disorder (which I'm having a hard time with right now but that's a different story). Lithium's main side effect is weight gain. I don't have the option of not taking it (trust me). I was wondering if anyone else took it and if they find it affects their weight loss much? I'm scared that it's playing a huge role in mine but like I said there's not much I can do.

Does anyone still lose while being on lithium? Do you lose like normal or slower?
