Lithium totally drained my energy i could no longer get through my gym sessions and was just miserable so i went back to pdoc after 5 weeks and he switched me to carbamazepine and I'm doing much better. If you aren't improving any it's always best to go talk to your pdoc don't suffer on because at the end of the day this is your life, your recovery and your choice . Give it a fair try and if you don't feel any better go back. Your pdoc is there to help. Good luck.
