Hello @pg92
Glad to hear you’re feeling brighter day by day and well done on the walk!
Only being able to manage bland food is boring but it’s food, and it will get better, so hold on in there.
I used to brush my teeth often to help with the horrible taste, as well as brushing my tongue with nice minty toothpaste. It only gave short relief but it was nice while it lasted. I also used bicarbonate of soda mixed in warm water mouthwash and gargle. Again, short lived but I guess it gave me something to do if nothing else.
As people have said, there are load of different anti sickness medicines, so tell your team and they can change you to something else next time. Ask if they could give you an IV dose alongside chemotherapy so it’s already in your system before you leave the hospital, then set your timer to take regularly after that, even if you don’t feel sick, to see if that manages it better? Your team will have seen it all before and know lots of different treatment options. This will hopefully reduce your fear.
Just before starting chemotherapy, I went for a really short hairstyle. One, so I didn’t have as much to lose, and two, so I, and others, got used to me with short hair. Then when it started to grow back in, it would look ‘normal’ quicker. Well, it made sense in my head at the time 
I got to a point where I found even the short style really prickly and painful when laying down. At that point I asked my husband to shave it off. From memory, I think it was about the start or middle of cycle 2 when it started coming out.
I finished chemotherapy treatment about 2.5 years ago and thankfully the memories do fade.
Knowledge is power and now you know what foodstuffs work for you, will probably change anti-sickness for next time, accept that you will doze lots rather than sleep (if you are on steroids, this may reduce once they stop) … you may find the next cycle isn’t as bad.
Fingers crossed.
Sending lots of hugs
