Many weird things will be happening to you right now. Try not to get anxious about new things. Try a variety of different food and drinks, whatever works. Don't be surprised when something you could tolerate this week is disgusting next week. Do whatever works to keep the machine working. Nutrition, hydration, toileting and rest and the four big things you need to get any way you can.

Be calm if you can. Try to separate the physical things from the emotional reaction to it, because that can make it all much worse. Remind yourself you've come a long way and you've done really well.
