Hey Mikey
I have been on prostap since April 2023 and completed Radiotherapy in January 2024.
I too have been experiencing both loss of taste and strange variations to tatse (eg had a creme brulee that tasted of smoked mackerel (only me - partner thought it was fine)). These taste episodes are becoming more frequest but are intermittent and don't seem to be getting worse. I finish prostap in February 2025, so can up-date then whether or not taste returns to normal.
I had thought this was just me, as I had not heard anyone else mention it, and maybe it was related to something else, a covid hangover maybe. Be interesting to see if others have their taste disrupted while on prostap.
