Like I said before, I used to do it regularly... I could still do it if I wanted to, but I just don't want to. It really doesn't fit with my daily schedule, lifestyle and goals right now. I've made many changes in my nutrition over the years...Who knows, maybe some day I'll try doing it again...Sometimes I will follow a certain style of eating for months or years and then change to something else for a while and then go back to what I doing previously.
