Well the one thing you know for sure is that the lemonade did not "create" the mucous.

Quitting during a "detox crisis" is not the "best thing" to do. You were actually having a "healing crisis' and if you can just start drinking lots and lots of fluid an/or even doing an enema to help the system get rid of the mucous and toxins would have been the best in the long run to really let the system and the lemonade work it's mojo.

What's done is done and after 2.5 days of eating your systems digestion got back up so it's gonna take a few days for the body to get back into fasting mode again. The wisdom when fasting is not to end on a low and to suck it up a let the body work through the healing crisis. The cayenne is great at lossening up mucous so if you can stand to add more then by all means go for it. Have an enema handy in case you start going through another healing crisis and just significantly up your fluid intake both lemonade and water.

Hang tough. What you went through was actually a good sign that your system was going through some serious detox. Be strong and fast through if it happens again and let the body go throught it's natural healing cycle and expell all that nasty stuff. Do an enema if you feel the need. Many folks have found instant relief from an enema during heavy detox.
