I don't feel physically different but mentally I do, I have made the decision to do this and I have a determination to get to my goal weight and with this tool I think I hope that I can do it. Everyday I am getting stronger and my body is adapting. I feel a little tired quicker and on occasion I get lightheaded if I stand up too quickly but its just until my body catches up and gets used to the weight loss. week 3 and its the only week that I have been interested in food, I wouldn't say hunger just I am more aware of people eating. my hubby had all sorts first two weeks and it didn't bother me but this week I've reigned him in coz I am starting to notice food more. Not hunger like before though as its still early days for me but I have had feelings of being full and knowing when I have had enough even on 3 tablespoons of food. They say 6 small meals a day but I have reached 4 meals. I feel that for me I have made the right decision, for me and my girls. With work I think depending on what type of work then 2 weeks just not lift anything heavy and bending is a little nippy on ur incisions but other than that its fine x
