weed will help with nausea. some people doont get nausea on 2ce others do. if you have nausea it wont be that bad either. trust me. sit down for a while, maybe smoke a couple bowls and it will pass. then you will be in heaven!
How experienced are you with 2C's? If not utilize only 10mg your first time around and see how you feel. Better to start off small and work your way up until you find the dose that you feel the most comfortable with.
