3 weeks out, still really new to this:-)

I just wanted to post to get some feed back from some of you who know more than me... So far I've lost 25 pounds which really has me syked!! I have had some vomiting, not to much though. I just moved to stage 3, puree or blended foods and now I feel like I might be eating to much? About half a cup is normal? I know I was a little over one or two times, I didn't get sick though. I guess it's just new territory and I would love to get some feed back from you. Thanks! Shaun
