Glad your posting!!. Ya took the day off yesterday but that's o.k.
Its normal for your counts to goto near zero so please don't get fixated w/ the numbers they're gonna change every time they test it..
Hope your throat clears up soon, and the hiccups will go away soon.
I would tell you to hold your breath for 5-6 minutes but I wouldn't want you to pass out
Better days ahead! Hang in there.
