It's not that unusual to feel that way following an initial cleansing enema or colon hydrotherapy treatment.
As the previous posters noted, your first enemas stirred up a lot of old stagnant waste matter that you need to eliminate. An enema first thing in the morning along with another at bedtime for a week or two may be necessary to cleanse your colon to the extent where you will feel rejuvenated and experience the sense of well being that a clean colon provides.
