It can be quite a harsh treatment if you overdo it. People vary in terms of how many sessions they need. I have had it done a few times, and yeah, you feel one heck of a lot lighter, but it can remove quite a few nutrients and you have to take tablets afterwards to replace the good stuff that is lost.
I was told by my irrigaitonist that for some people the stuff inside of them is so hard it is like firing a waterpistol onto a brick wall, and nothing comes out. I went through a phase of suffering from bloating, so i did this but also received a lot of advice on how to change my diet.
When the thing goes up your bum, you don't feel violated or anything. It can be covered in very cold gel though, and when you poo you cant help but think it will go all over the bed and floor but it doesnt – it goes through the tube.
The tube is made of glass so that the irrigaitonist can look at your poo and tell you what is wrong with you – there are all sorts of types of poo and stuff and they are the experts.
Also, it can really make you want to pee, and I had problems not wanting to stop and go to the loo. At the end you poo a whole load of water out again when on the loo, but yeah, it's ok and you feel really good and a little bit high 😀
