hey, so I've been having these real bad headaches the last few days, and I never really thought much of them, just took some ibruprofen and moved on. I have a 5 gallon carboy fermenting vigorously right by my desk, and I told my friend this, and he thought that it might be from the carbon dioxide the carboy is releasing is the cause of my headaches. My apartment bedroom is pretty small, maybe 10x10. I dont think this is the case, but I figured I should check. Thanks
