I had the same experience, Gemma. Having to pee every 45m all night long is an absolute killer in terms of sheer exhaustion. What I ended up doing was buying a plastic urine bottle from Amazon. Didn’t stop the need to pee, but it meant I didn’t have to get out of bed, and that made a huge difference in terms of being able to get back to sleep until the next time.
It’s just a case of getting through it, I’m afraid. The good news is that the frequent peeing should ease off relatively rapidly after RT finishes. For me the side-effects peaked about 10 days after the end of RT, and a fortnight after that I was peeing pretty normally again. I finished RT in late March, so five months ago, and I’m still taking Tamsulosin every other day now to help with flow.
Cheers,
Chris
