Hi, Sophie!!! Welcome to the 30 somethings forum at 3 Fat Chick's. Changing your life style is a good thing, and starting out small is a good idea.
We usually post on the thread entitled "Week of (what ever that Sunday's date is)" Who ever checks in first tomorrow morning will start the new thread, "Week of April 28th". that is where we all check in to give each other support and encouragement (and a little chit chat along the way!) I do hope you join us; talking to others who are going through the same sort of life change is very helpful! I know it has been for me.
May you be
