If this is first time there will be some awkward feelings as such. Hope you are not intending to try again and become addicted or dependent. Then no help will be of use as you will be messing your life completely.
Ok, if this is first time and you don't want to do this again, consult your doctor and be honest to tell the doc who can give you some relief medication from nausea feeling
Next Steps
Any doctor can help you but don't ignore or delay. God bless
