Welcome to the forum, yarema, good to hear from you!
I can tell you my experience. I am just 7 weeks after robotic surgery. I am dry most of the time unless I wait too long between visits to the restroom. I am dry at night.
My good friends here, recommending that I "go" every 1 1/2 hours whether I needed to or not. I did that and it helped a lot, along with the Kegels.
Yesterday, my doctor asked me to wait for the physical therapy (PT) with biofeedback until 3 months. If I wasn't satisfied with my progress by then, she fully endorses me having PT to strenghen the pelvic floor. If you choose the PT route, you may wish to secure one or two recommendations from your urologist/surgeon. We have a rehab hospital locally with PTs skilled in biofeedback for treating incontinence.
Do you feel as if you have made any progress as you do your Kegels? The advantage of the PT is that they can determine where you are weak and whether or not you are doing your Kegels properly.
Also, I'd say stay away from caffeinated drinks! These will break your continence and confidence pretty quickly!
Lastly, some folks don't gain full continence for a long time, perhaps one year or more. From what I've seen in the forum, at less than 4 months post surgery, you do have a lot of hope for continence ahead of you.
All the best,
