I did take an impact test a day before I was cleared and the results came back better than my initial test I took before even getting a concussion. I was cleared this last Thursday, started up water polo practice again, and she gave me the okay to drink. I drank that weekend and regretfully did cocaine and starting getting symptoms of PCS again this Monday. I got a pretty uncomfortable migraine and an anxiety attack that Monday night and early that Tuesday but has worn off. Would it be okay to start up practice again this Thursday? I drank Friday night and felt fine Saturday and Sunday.
