Medications and libido

I was diagnosed as bipolar many years ago but only started taking meds 3 years ago. Before the meds, I had an extremely high sex drive and even on the meds there wasn’t too much change. However, I was so slow and sluggish and didn’t realize how out of my element I was until my psychiatrist refused to see me as a patient anymore when I missed an appointment (part of some contract). Once I finished going through the withdrawals I realized how great I felt; I was alive again. Except for one thing. I had lost my sex drive. In fact, I hardly even fantasize anymore. This has made me extremely depressed and it’s hard on my marriage. Has anyone else experienced and issue like this and overcome it?
