Day 4 and feeling FULL

I've cleansed before (colon) with a different method and had BM's like crazy. This time, it's only a little mucous stuff..No REAL action. I'm extremely bloated, have lost no weight. I did the SWF (Salt-Water-Flush) first day, but almost threw up. Realized today the Sea Salt I was using had additives (something to prevent from caking). So after work I'm going to go to Trader Joes and get some unrefined salt. I've been taking the senna tea a.m. and p.m.; doing P&B shakes, drinking 12 lemonades per day and the appropriate amount of water for my weight and still no real action. I know the importance of getting this stuff out but I'm getting worried because I'm having no results. I had more BM's before starting the fast. Any words of advice, consulation or suggestions would be much appreciated
