Cougardad -

Get some ISOSOURCE and start pushing it through the pump. I do 9 boxes per day at 3375 cal. Takes some time but I can maintain my weight at 250+/-. Do this now. The downward spiral of weight loss and the ability to withstand current and near future treatments is a tough one to break out of.

Personally, I would recommend the unflavored "feed". (My term) The unflavored is a bit easier to deal with when you have to vomit. But, if your a glutton for punishment, it comes in vanilla also.

Set your pump at a rate that will provide the feed in a manner that will not introduce additional distress to your system. (Too fast and sometimes you'll end up with a bloated / sloshy feeling similar to drinking to much water. That could also lead to vomiting.)

You also need to consider how painkillers impact how your bowels process waste. (Opioids slow down the process.) The worst is when you keep pumping the feed in AND your constipated from the pain meds. (Highly recommend using laxatives to reduce the potential for adverse impacts due to constipation.)

The thick mucus is something that I still struggle with daily, although the volume has reduced over the years since surgery.

The next six to ten weeks will test your resolve. Keep focused. Try to take in and hold as many calories as possible. Rest / sleep when you're tired, (and even when your not.)

Good Luck
