It was. I'm fairly confident thata where a good amount of my forgetfullness has come from. I barely had the energy to do anything more than sleep. Eating was almost off the table the entire time (scary thing is I didn't even feel hungry during it and it was over 2 weeks of little eating) and it took a good month or two before I was able to even feed and water the birds without gasping for air. Another few months before I was back to normal breathing wise.Yuck. That sounds miserable.
