Agree with everything JO said above.
Id defo say ten and Im not far in and have found restriction with my first fill then it when. Had a wobbly few weeks but then realised i can't rely solely on the band, i took the excitement i had in the very early stages and started keeping a food journal religiously and exercising. Now Im feeling really proud of myself and healthier in myself.
BE PREPARED to feel like you don't even have a band in the beginning, i don't mean this in a bad way at all, if anything it means you've healed really well but i wasn't so prepared for that so i took advantage of it on occasion and it got me rather down.
Good luck Im really excited for you and to see how you get on!x
