I'm sorry your having difficult time of it. Chemo treats us all differently. The side effects will be bad for one person, and the next not be bothered at all. I had the hairy tongue feeling. Sores in my mouth, got sick for 3 days at a time, lost a bunch of weight. Some of the steroids just about drove me nuts, I had to stop them. So, yes much of what you are feeling is normal, but always, always call your doctor and tell them exactly what is happening. They have seen almost everything that has happened, and will usually have an answer.
Try to catch your breath and just know that everything your going through, lots of us have been there, and doing ok now. I've been at it for 25 years and still kicking pretty good.
If you have any questions please ask.
