I would go for it. I don't know how much a lot of money is for you, but I would think that feeling great is worth the cost.
I decided to start cleansing a couple of years ago after reading about it. My first cleanse , I purchased online through a company called Young Living. At the time, I had a pain on the right side of my stomach in an area where the ileocecal valve is located. The ileocecal valve is the area between the large and small intestine. Food travels down, the valve opens and the food moves into the colon and than the valve shuts. For some reason, my valve would remain open, and the pain I was experiencing was probably some of that food going back up where it does not belong. I had this problem for at least a year and a half. Sometimes I would move wrong in my sleep and the sharp pain was so bad it would wake me up. I did not know what to do. My massage therapist showed my how to shut it with massage, which worked temporarily, but eventually it would start hurting again. After doing my cleanse, the pain has been gone for at least 2 years now. I don't know if it was the colon cleanse or some kind of parasite causing the problem, but that major annoyance and pain is gone.
I would definitely recommend a cleanse to anyone willing to give it a try. It is well worth it. I have way more energy and health now, than I did before.
I now do regular cleansing for maintenance. My favorite cleansing products are by Young Living, Isagenix, and parasite cleansed by Clarkia. Every few months I do a colon cleanse and about 2 or three times a year, right after my colon cleanses, I do a parasite cleanse.
I also have an Isagenix protein shake and supplements every morning.
I hope this helps of removes any doubt about the positive benefits of cleansing.
