Another incontinence questions, looking for similar experiences

My RP was about 3 months ago. I still have 0 control of urine when I'm standing/walking/moving, generally small amounts spurt out every minute or two (clearly it's not staying in the bladder). When I'm sitting, it generally doesn't leak out, and if I contract the pelvic floor on my way to the toilet, can usually empty fairly normally. At night it's kind of 1/2 and 1/2. When I wake (frequently) I'll get to the toilet and empty what's there, although if I sleep more soundly then it drains into the pad. Two months post op I had a pelvic scan as well as a cystoscopy, nothing abnormal has been revealed. During the cystoscopy the doctor had me tighten the external sphincter, which I did just fine. The PT guy also says that everything seems normal. I've been pulling up on the kegels since the catheter was removed post op. I've been doing various physical exercises for pelvic floor muscles, etc. So far nothing has made any difference to the issue. All the medical professionals are basically saying: "Hopefully it will improve." Any of you guys have a similar experience? Has anyone used one of those biofeedback gizmos with any success? I'm 67, fit, active, fairly slim.
