I ended up just drinking water during my chemo, and that was very much just a routine thing as it's important to drink lots and stay well-hydrated, it wasn't for 'the taste'.
If it is that your taste has been dulled then try and find strong tasting drinks like fruit juice etc. but just be careful with the sugar content and you teeth. Maybe get sugar free squash and just make particularly strong squash drinks? Sadly it's a little bit trial and error as to what you can and can't taste. It might be that you can taste mint particularly well compared to other flavours so maybe mint hot chocolate might work?
Sorry that's probably not much use but how it affects our taste is so individual so it really is trial and error.
Hope you find something. Still, remember to force yourself to drink water at least.
