Teeth troubles

Hey ladies! Just got my root canal done a little over an hour go. Feel awesome. Before the procedure I couldn't eat or barely talk it hurt so bad. I had an infection causing all this pressure and severe pain in my tooth.  I was put on heavy antibiotics which made me have stomach issues. Anyone have any suggestions as to what foods to stay away from? Should I limit my usuage of chewing on that side, and what your experiences after having a root canal was like. Pain? Anything? How long did it last afterwards?
