Beyond thirsty

I just finished my 6 weeks of chemotherapy and have only a handful of radiation treatments remaining (8) and to say it’s been a living nightmare is an understatement, but I knew what to expect and feel like I’ve dealt with it all reasonably well.
My question is this, is there any thing I can drink that taste as close to natural as can be?
Nothing I’ve tried is really going to well due to metallic taste or no taste at all. I’m using a feeding tube for my nutrition and it’s going good, I’m retaining my weight and don’t really think of solid foods most of the time but I would give anything to be able to drink something that has a good taste as this is what I’m missing the most.
If anyone can suggest something, I’m all ears. I feel like I’ve tried everything the Drs and nurses and the internet have suggested to no avail. I’d like to hear from others who have actually been through this. Any and all help appreciated, thank you.
