If you're feeling unpleasant then it is not a good idea to take more DXM. It will just make you feel worse, and for longer. It's also probably not worth doing it again if you don't like the experience the first time.
Occasional usage of DXM does not cause brain damage, esp. not at the 6 oz level. You will be just fine even though it may take a few days to get back to 100% normality.
William White, I think said, about 1/3 of people who try DXM will like it, 1/3 will find it boring or not worth their time, and 1/3 will strongly dislike the experience. It is actually really common for people to try DXM and find that all it does is make them feel very weird or sick.
The best option you have is to ride it out. Try and make the best of your high. Find a cheesy movie to watch, or lay down and listen to music. Have something light like a warm cup of tea or a few pieces of fruit or veg. Maybe try doodling or type out your experience as a trip report if you feel up to it. Don't take any more drugs, you will just get more fucked up, which is not going to make you feel better.
You may still feel a little funny the days after a DXM trip. Don't panic, it's a totally normal side effect from the long lived metabolites of DXM and will resolve in time. Having lots of fluids and getting some exercise to help your body metabolize them will definitely help.
