For those of you who have done the Miralax and Dulcolax pill prep, how long after you started the prep before your first trip to the bathroom?

It took about 7 hours to start on me, but I had stricturing in my colon, so Im not sure how long its supposed to take. =( Good Luck =)
20 yr old female, dx'd in 02, struggled for a year with controlling this retarded disease. Finally got on Remicade(miracle drug for me-at the time) was in remission until summer of 09. Remicade stopped working, switched to Humira. Had my first surgery, half the colon and some of the small intestine removed. developed abscesses. it was messy. Currently on no Crohns meds, going to probably start the Humira again soon.

It was 6-7 hours for me as well, and I had no stricturing. I was very surprised at how long it took. Once it started working, however, everything got moving *very* quickly.

I always have a hard time getting cleaned out, as it takes way too long to start and then I'm still going the morning of the procedure.  I don't remember the name of the pills they usually give me now (huge pills that you take every 15 minutes), but I start throwing them up half way through taking them and then don't take the rest (or throw them back up whole, if I do).  Then, I don't start going until the middle of the night or the morning of the procedure and they always make the comment about me having bad prep on the reports.  I'm always worried when I'm still going to the bathroom right before they knock me out...what if I go on the table while I'm sedated?  But, they've never said that I did that, so hopefully it has't happened.  =)
