The thing with these questions....we all KNOW the answer. People KNOW that they shouldn't run certain things back-to-back, or for so long, or have a drink...whatever.
NOBODY on this board is gonna say, "Nawwww...you'll be fine. Go for it!"
We all know the risks, we all TAKE the risks. Honestly...you're gonna do what you're gonna do. Are you gonna die? Probably not.
Just make sure you do end up taking some time off and try not to get TOO out of hand with it.
