Grand Valley State University 1st Time MIP

There were at least 4 officers around the dorm room I was in. I walked out with no alcohol on me and they said I was obviously huffing something just because my eyes were red. As I was clearly not huffing anything they asked me if I would take a breathalyzer test to which I refused. They gave me the eye test (note that I was sick all week and I spent the majority of the day sleeping) and I guess I didn't pass. They asked if I had alcohol and I said no. They asked if I would let them into the room, to which I also refused because they did not have a warrant. At this point I am surrounded by officers and a crowd of students watching to which made me very nervous. I said I drank out of a random girl's water bottle never saying what was in it. That's when I got slapped with an MIP. What now?
