Energy Loss

Hi hopefully your all doing OK 

 I recently had a major Pancreatitis attack,, They were dumbfounded of the cause and assume its the cancer that is all throughout my abdomen.,, Now Im on a no fat diet between that and the 35mg of pain meds I take.. I was told before the cancer feeds off your food intake,, so Im getting much worse as for energy.. Do any of you take anything to boost energy level..

Thank You !!!! Greg
