I found that I would drain a bit at the clinic bathroom just before going in for my daily treatment. That worked just about perfectly for me. Usually when I went into treatment, I would feel "comfortably uncomfortable" which I took to mean that I was ready. Two incidents, though:
- One Monday, I was told that I was borderline low, but okay to do the treatment. Probably due to my "normal" hydrating over the weekend.
- Last Thursday, I was "too low" so I had to get off the table, drink some water and come back "in a bit". The techs found out after my treatment that day what happens when I overfill my bladder. Wet blankets, a wet shirt, a real mess! Needless to say, I was a little nervous over my last 4 sessions that I'd have a similar low bladder situation, but I was fine. Treatments, thankfully, are now over, and I don't have to abuse my bladder for the foreseeable future.
Keep the faith, all. There is a light at the end of the tunnel and perhaps a cow bell to ring when you are done, as my clinic does in celebration!
