it's bad stuff, I had one friend who was admitted to the hospital for 3 days after respiratory issues and it's gone through a bunch of my guys at work. they've all been out of commission for 4+ days once they got it. One guy has been struggling for 9 days now and I'm afraid he's going to end up in the hospital too. Take care and don't wait till you're at the end of your rope to get help if it's not getting better.
