I heard the start of the show and he said he was tired.
Gee, if he has been ingesting that much stuff (very doubtful) imagine how much better he will be on air if he gets himself straightened out.
I don't think Rush Limbaugh is going anywhere. But what if he did? He's pulled in 100+ million in the last 36 months. So, if he is "toast" he's "buttered toast". With diamonds.
I've listened to Rush Limbaugh on and off and other than when his hearing was going he's never sounded high.
No matter what, I wish him well.
