The more you can get through the detox crisises, the easier it will be next time. I do the same as you, soon as i feel dizzy or weak, i get nervous and end it. Next time i will ride it out. If we get through to the other side, our confidence will grow each time we do that.
My hubby has a week off next week and we plan to do a fast together, as we did a short one a week ago and he lost 4lb, and he only regained a pound of that, so he is eager to do another one. He has also cut out the big meals he has when he is away.
So it will be nice to have each other as support, but i hope to go longer than him, as he is only planning another short fast due to working the following week. He travels long distance to work so can't really fast and work.
