It's an extremely sensitive area and anything can set you back. 17 days is still very early stages.
After two years of every day use I am able to reduce my dose to six days a week and hoping to reduce further as time goes on.
A virus, stress, doing anything physical like gardening, bending down too much will have me going to the loo more often, always starts with the need to pee, but it soon passes. It's all about patience!
