Welcome to PC!!!!!
Sorry that you are really struggling at the moment.
There are lots of drugs that are out there, personally I didn't like Tegretol but it works for some people. If its not helping you then maybe you need to try something different. As roxiesmom says, people with BP generally need a mood stabliser like lithium, lamotrigine, epilium etc. Who is prescribing your meds? Are you seeing a pdoc?

I'm not sure what IOP is either. Please keep on posting and I'll try to get back to you if I can help
