I would HIGHLY suggest the Leptin Reset. I had issues with carbs and starches after R2, then did a R3 trying to recoup my losses. Instead of following the P3 protocol, I went directly into the Leptin Reset. I have NEVER been more stable in my life! After reaching Leptin Sensitivity, I CAN have carbs, sugars, starches with NO ill effect. For you to have such a severe reaction, your body is desperately trying to tell you something! R3 LIW was 127# in October 2011 - today I'm at 124.8#, no kidding. Its FABULOUS.
