I had the higher dose also, my anxiety hit the roof, plus several UTI's ended up with a Foley, guess one thing the Botox settled down the spasms and the Foley was accepted so well by my urinary system. My Dr.'s are fine with that. They continue to push Botox here.
Right now I continue to self cath 6 times per day, and periodic large Foley's for dilation ordered by the urologist
And oops, no hair, much better I guess to control
