am I overdoing my cleanse? Advise please!

am going to have a colonic clease tomorrow. Today I am fasting on jucies and eating some salad to prepare, also taking psyllium husks veg caps. I figure tonight I will do an emema of garlic and Epsom Salt and a day or so after my colonic do a detox using a detox tea that I used in the past. ( I lost 8 lbs in one week using the tea) Am I harming my colon or intestines? Im drinking plenty of water.
