do you get less nausea when you IV compared to oral?

whether you're IV'ing hydromorphone, oxys, or H, do you get less nausea when you slam them compared to when you take them orally?

 

No, the nausea hits you faster.

 

Hydromorphone and heroin have really lousy bioavailabilty orally anyway. Oddly I have noticed I can shoot a morphine 100 and be fine, but if I ate it I would probably get nausea.

 

yeah I knew that, but say compared to when you have eaten oxy's or any opiate with comparable strength.
