Hi there, I know what u are going thru. I did not stay in the hospital but 2 days, but the next week was hell! I had the hardest time getting anything down. Have you been walking? U must get up and walk many times a day! That is what helps ur lungs get cleared out, plus it helps the healing process begin and u will feel so much better!! U r OK on fluids while in the hospital, u r basicly teaching ur stomach how to handle fluids. Keep trying, teeny tiny sips at a time. Crystal lite is still the only thing that settles easy and it has got to be cold!!! I was concerned about getting dehydrated after leaving the hospital, I made sure I got my fluids in so please be sure to do that, it is so very important. U don't want to go there!!! A little tip about Crystal Light, I have to use one individual pkg per 32 oz of water, 16 oz makes it too sweet! I hope this helps and I will answer any questions I can! Good luck, hope u feel better real soon! Oh, and no appetite is totally normal! It will come back!
