I have noticed over the past several months that I have been getting the hiccups like 4-8 times a day and it's getting really old. I take Keppra for seizures, Cyclobenzaprine (muscle relaxer) and Xanax at night to help me sleep(otherwise I'd just have a series of panic attacks all night). I also occasionally take Darvocet for icepick headaches. Anyone know if hiccups is a side effect of any of these?
