Most of my thoughts on my experiments with IF (all positive) are sprinkled throughout that thread, so you can glance at that for my experiences thus far
Also, just posted this in response to a similar question in a different forum: March 2011 Chat!
Feel free to ask any questions to follow up, but you may want to pose this question in the Anyone Else do IF (Intermittent Fasting)? thread because you can see the thoughts of many different people, including those who've been doing this for a year+. Just a helpful source of info all consolidated there and people already involved in that thread ready to discuss IF, so you may get more traction on your questions.
