However i went on leave last month and gained a few inches on my waist i have been excersicing like mad to get them off but the last inch and a half is holding on tight. I plan on siting in the sauna on saterday and sunday for an hour each day and limiting salt intake and not drinking or i have to keep it to a minnum. and saterday and sunday wrapping my body in saran wrap and preperation h before i go to bed. However i heard that an enima saterday or sunday will help for monday morning in takeing off that inch and a half for monday. I just need to get rid of it for monday morning after that i can get back to the right way of doing things. Will an enima help ? Help, my promotion hangs in the balence.
