Options
Hi. I,m newer here, usually on reddit lose/it but a lot of people seem to be on both sites. I have been working on my weight for about 4 month and have so far lost about 2 sizes, appr 40-50 pounds, not 100% sure as I don,t weigh, I know if I did I would get discouraged as I,m no where close to where I want to be. Looking for extra friends wanting to lose a lot of weight too. Got a ways to go, and we all could kick each other in the butts when we need. Looking to keep my motivation going coming up and into 2015, last time I lost weight I lost motivation at about the 3 month mark, I,m still going strong right now but have had a couple hic up days over the holidays and don,t want to falter.
