I have been exclusively on Jevity 1.5 since March of last year or about 11 months and while certainly not optional, it will work. I started out at 119 lbs after getting out of the hospital with a PEG tube (I did better the first time around w/o a PEG) and 6 cans a day of Jevity 1.5 plus a beer or wine have put me up to 136. I'm still 5'11" so I also know what it is to be considered skinny

Keep the Faith, you will do just fine
