Do you have someone else to go with you? It does often tend to be a drawn-out affair, but you never know.
How favourable is your cervix looking? When were you due? The gels generally get your cervix riper and ready for AROM and syntocin. Sometimes they are enough to kick-start labour, but often not.
I didn't have gels, I had tape & balloon put in the night before. The next monring my cervix was still high and fairly firm! So it all just depends.
