Ask your doc for an open prescription to get hydrated in the chemo lab. This will help you to feel better.

If your daily intake isnt at least 2500 calories and 48-60 oz of water, then you probably will struggle thru your treatments. Its very early in the game to run into any problems, but everyone is different. Some can have problems from day 1 while some other lucky patients sail right thru without hardly a bump in the road. The common denominator is patients who have it easy are the ones who focused on getting their daily minimums in no matter what. I cant stress this enough... it really will make or break your treatments if you can or cant get the daily minimums in.

As far as the PEG goes, its a very personal decision. Many are pro while others are con and think most can get thru it without one. The PEG wars got pretty ugly with each side being adamant on over-stating why their way was best. Its a tool that will make things easier in many ways if its used correctly, as a supplement to eating/drinking. Whatever is best for you in yoru situation is what we will support you with.

Best wishes!
