Ernie and I made it about 3 weeks back on regular food after our three week cleanse. We feel like crap - fat has started to reappear on our tummies, mucus in our noses and general lethargy has re-entered our lives.
So, we're back on Clean, but with some modifications. We won't be as strict on the weekends when it's really tough to stick to the program (especially no drinking). I'm also going to be eating corn and potatoes. I'm not too sure why you can't eat those veggies on the program.
I guess this is a good testament that the Clean Program actually can change your life. I highly recommend it.
