Don, I am 23 years old and I'm Bipolar as well, In the past 5 years I been on almost every psych med there is out, I have been in the psych hospital several times which isnt fun. In that time period I began having leaks which just got worse over the years. The meds I'm on now is Lithium, Zoloft, trilafon and restiral for sleep.
The med combination keeps my moods stable but caused me to have OAB and spasmodic bladder/bedwetting and IBS which causes me to have fecal incontinence do to diahrrea. I now have to wear diapers 24/7 it definetly sucks especially a person at my age but the bright side is the meds I take keep my moods stable which keeps me out of the psych hospital and if I had to pick the psych hospital or wear diapers I would pick the diapers because the hospital is not fun at all, and after all a diaper in a nutshell is just an absorbent peice of clothing that lets you go throught the day and gives you the freedom to do whatever you want instead of being locked up, unstable and bored out of your mind. Only thing that really bums me out is trying to find a girlfriend, that will be extremely difficult

I have had the same experience s you with urologist/ GI doctors for the past couple of years and both of the doctors I go to think its do to my psych meds that I take. I just wanted to let you know Don you are not alone, I relate to you a lot and I feel like I'm in the same boat as you are.
