Sweety - my sister is having the same issue - see my post re; weight gain. Cathy was really having problems with her swallowing after surgery so when radiation started she wanted a PEG tube. Because of side effects with radiation she has been in hospital since May 18th. She is now on high cal Resource 2.0 and has been having 3 a day for about 1400 calories so she (hopefully) won't lose anymore - (she started at 100 and is now 83 pounds) and she is working on upping that little by little up to 4 a day which would be 1900 cal - so at her size she should put some weight on. There is no way she could get to consuming 3000 calories a day - that is just too much volume for her to ingest.
