Sounds like you are doing primarily green juices, which would have been my first suggestion... are you drinking fruit juices? If so, the Sugar can gas and bloat you up... stick to the green stuff. Be sure to drink enough plain water.
If you still have trouble, you could try drinking water for a day and see if that helps... sounds like you're almost there!
Also, are you sure your colon is clean? If it is congested this could be a good part of your trouble. I would do a plain water enema to be sure. A professional colonic would be even better; it is truly amazing the things that can come out of you, even after 60 days of fasting, and nothing gets the gunk out better than a pro colonic.!
