Getting off of diclegis...

Debbie
I have been taking diclegis since week 6 and I'm now at week 14.  I was wondering if anyone successfully has gotten off of it and how they did it.  I think it's giving me terrible headaches and would like to try to wean myself off.  I am skipping my dose for tonight to see what happens, but trying to see what you ladies have done.  I am currently on the max which is 4 pills/day.  I take one at 7am, one at 4pm, and two at 10 pm.  I was thinking of skipping the 10pm for a few days then the 4 for a few days then completely go off.
