I agree with everyone who has said to try an NG tube first. I gained about 15 pounds over three months using it three to four times per week. It was great because it was something you could put down at night and take out in the morning. Unfortunately, I lack enough self-discipline to keep up with this and have agreed to a g-tube and am going to see the GI doc in a week. Less discomfort, less work, and I can gain the weight back. If you have the will power for an NG, I would definitely try that first! Good luck!
