I'm not a pepper person and tend to sip my lemonaid all day. So what I do is put in a pinch of pepper and a dash of lemonaid and chug it down...then pour the rest. In short - I eat the pepper first and don't let it sit in my glass...or it gets way too hot the longer it sits.
I've also had to be careful because too much means I will get an upset stomach and burned bum. I definitely cut way back and the problem stopped.
