I'm on day 13 as well and feeling pretty good. I had a heckuva time with body aches on days 5-7...majorly bad! But have been feeling good ever since. My energy isn't what it usually is and I have not been able to run my usual 5 miles per day, but I have been taking really long walks. I'm very happy with the cleansing process and can't wait to see what other junk I can get rid of in the next week! My husband started with me and has had no negative side affects, great BM's and looks thinner than I have seen him in years. Not entirely fair considering I have been a very conscientous vegetarian for the last 15 years, and he eats anything he wants! But hey thats men for ya, they have an easier time at these things it seeems. I'm happy for him because he's always a bit concerned (if not paranoid) about colon health.
We have both spent alot of time fantasizing about what we will eat after coming off....but it's all fantasy because we only eat one meal a day at around 4:00 pm and we've always been that way. It's fun to dream though!
All in all it has been a very gratifying and positive experience for us both...and I thank you all for being here. We're hanging in till day 21, and I've heard talk that some of the best benefits come between days 15-21 so bring it on! Glad to have found a fellow 13 dayer!
