My experience so far... after 30 minutes, my face started feeling very warm. Like, if the sun was on your face on a hot summer day. That feeling lasted for about 20-30 minutes, then went away. Now, 4 hours into my first day, so far, so good.
Just to let you know, I read Ladymac's post, and I'm going to try following her advice.
God Bless!
