I have. Actually there has been a small number of them hereabouts since this crap began. I find myself getting sleepy with the single mask I have to wear at work. Two would maybe knock me out. Mask wearing here is a bit less insisted upon than other places. Only a few stores actually enforce it. I have to wear one at work because the shipbuilding company has federal contracts now but I wear it under my nose and no one worries about it, so long as it is on my face.
Getting sleepy?
Probably a lack of OXYGEN from wearing a stupid mask !!!!
