Alexis, your reaction following your first colonic is not an uncommon one. Expectations for a procedure costing in the range generally of $60 - $80 for a single session are often unreasonably high.
You can often get a discount on the price if you sign up in advance for a series of 6 or more over an extended period.
The problems that motivate many people to seek colon hydrotherapy didn't occur overnight, and they won't be resolved over night either.
I encourage you not to give up this easily. Stick with it for a few months and I'll wager you will have a much more positive perspective on the benefits you have achieved with the help of colonics.
