I had a similar problem. I found the solution wasn't switching mixes, it was to make sure my wick was SUPER wet at all times. If it wasn't, it was like my throat got a blast of nasty.
If it was, I got a nice heavy vapor.
A short term solution is coca cola. Get a coke, drink it, proplems go away for an hour.
