What can you mix with DXM?

I took roughly 180 mg of DXM about 2 hours ago. It's starting to work. I got invited to a party tonight, a friend is going to pick me up. There will probably be Alcohol and weed there- Possibly shrooms. What can I mix? Also please no brainwashed middle schoolers or ignorant right wingers preaching to me. I am an adult with a job, a degree, and a good life and it's none of the government's business what I do in my free time.
