Correctol usage

I have never been regular in my bowel movements. Lately I have been using Correctol 2 or 3 time a week.  I take 1 tablet at bedtime and by the time I get up the next morning, I'm ready for a movement.  It's a little difficult to get it started, but after the initial expulsion, the rest is more like diarrhea. I don't feel like it is causing any problems, in fact I fell better having more regualr bowel movements.  Is ther any danger in taking 1 Correctol table a day 3 times a week?
