Any suggestions?

I am a bipolar on meds. Things have been better recently i am going through less episodes. But once per week a dejavu knocks on my door..It was much frequent before so i dont see it as a really big problem. Actually i havent told anyone including my doctor about it because i am scared of more drugs.After some exploration i found out epilepsy patients suffer from it.. The dejavu is usually verbal an inside voice tells me a word sometimes few words and after few hours i come across the exact word at a movie or something i am reading..i dont know what this is? it felt spooky before but i got used to it now. Also i am a heavy smoker trying to quit unfortunateley whenever i try it gets worser..so i stopped trying to quit. Maybe it has something to do with it..is there anyone who experiences something similar. thank you already.
