It's good that you can afford the colonics. On the other hand, you'll need some type of colon hydrotherapy for a very long time so you might just do it yourself.
The coffee enemas are very effective but you need to retain a very small amount in the sigmoid.
As to reflorestation, you can add some kefir to a clear water enema and retain it for a while. I do this after every enema now.
Make sure you use chlorine-free water.
