I was pressured by my doctors to get mine. I was 100 pds and 5'3. I got sick of the pestering and said fine id do it to shut them up. I had been in the hospital for two weeks when I told them Id do it, they extended my stay for two more weeks to get my gjtube put in. I was conviced it would really help, the way they praised the thing I was ok with it. When I had it put in I have low pain tolerence so they kept trying to dose me up on pain killers so I would breathe better.(During the sugery they decided to douse my lungs with pulmozyme directly so when I woke up i felt like i was drowing in mucus.)After a total stay of 1 1/2 months I went home and used it. I had used it for over half a year and only gained 5 lousy pounds and didnt grow a bit. I quit using it. On my own I have gained 15 pounds but I tend to yoyo a lot in supposed to be 120. im now 5'4. The sucky thing is that Ive had it for 2 or 3 yrs and Ive had to replace it 6 times due to the balloon bursting or it falling out or the J part winding back into my stomach area. Im now 17 and they refuse to remove it and Ive told them Im never using it again. So you cant just get it removed whenever you want odds are your going to have to prove yourself to them.
But if you do need it get it because im sure from all of these other good comments on it, it would work better on someone that actually follows through with the directions.
Good luck with your decision
