The weight loss is totally manageable & does not go straight back on at all. The mistake I made first time round was to presume that the elation I felt about being slim & the happiness I felt at being a different person (my behaviour also changed as I lost weight) was enough to keep me slim. Maybe it is for some people, but I didn't get overweight by eating too big portions or not exercising. I got fat because I'm a binge eater who used food in a destructive way & have all sorts of horrific habits. This time round, I know that being slim & feeling good isn't enough to beat my demons. I have to put other systems in place. This time I'm using my time in abstinence to see when I am craving food & why. To acknowledge that I can get through these cravings & how surprisingly easy it is. I also doubt I'll stay on sole source long, rather move up to 810 & introduce regular exercise so that that becomes the norm by the time I'm eating again. And consider other things too, such as transferring some of the things from ss that have helped me, such as removing the choice & having structure. Maybe having the same breakfast & morning snack every day. Maybe making meal plans in advance. I'm not sure yet what will help, but at least this time I know that, for me, being slim is not enough. Sorry for rambling, hope this helps!
