Norco is a stronger Vicodin. So if Vicodin makes your vomit in 20 minutes, then Norco will probably have you vomiting in 10... we wouldn't want our little lampchop throwing up all the time!
Ask about the Neurotin. Maybe 1/2 dose of dilantin? It's for the same kind of pain...I know that stuff put me to sleep so maybe it's not a good idea, but it did help...just a thought.
Get better...
