has anyone on dilantin had any problems with constipation. i have been takin it since august of 2002 and here recently i have been having problems with constipation and i thought maybe it was the meds, because i never had a problem going before i started them.

Constipation is one of the side effects listed in the PDR. If you're not already drinking lots of water (you should be, if you're on Dilantin), then start.
