I Just Started Carbamazepine. I Also Take Warfarin And Diltiazem

I just started carbamazepine. I also take warfarin and diltiazem and metropoal for heart. Today while walking all of a sudden my legs did not want to work. My feet were there, but my brain could not get them to move...after a few seconds I was able to go again, but was really wobbly. Now, I am afraid to take my pills for tonight..
