Your body is probably absorbing salt and therefore retaining water which prevents you seeing your weight go down and the bloating. To resolve and determine what's going on you need to follow the Master-Cleanse protocol. What is in those pills, what effects will it have with the MC? I'm not asking for info, I'm asking if you know what you are doing?
First take the senna tea (Smooth Move) before bed. Take the Smooth Move again in the morning and again in the evening. See if your bloating has reduced on Saturday morning. If so do the SWF (Salt-Water-Flush) in the AM and the laxitive, senna tea at night and then go from there. I think you may find you'll be OK unless your sensitive to salt as my body was during this past MC. So, I skipped the SWF (Salt-Water-Flush) every other day. The one other thing you can do is take your blood pressure because in some it will increase with increased bodily fluids that are causing your bloating.
