When do we know that we need a colon cleansing?

When do we know when to do the colon cleansing?

1. when our excretion becomes sticky and smelly
2. when our excretion becomes darker and smaller, not continuous flow
3. when our stomach feels bloating
4. when one spend too much time in the toilet trying to excrete
5. when one excretes once only in 2 to 3 days time but eat 3 meals a day
6. for someone who always hold back his or her excretion

Remember our small baby's excretion?  They are big, yellowish and continuous.. and coming out fast!  well, this is the standard for all...  Best to ask for professional aids.
