The medicinal taste of some whisky is usually an acquired taste. If you want something smoky without the iodine, try Highland Park 12. It's available widely and around $50. It's not too powerful and complex and is a good place to start. Another common whisky flavor is sherry from aging in sherry casks. A nice sherried single malt that is widely available is Macallan. Go with the cask strength if you can find it.
Go to a good liquor store and ask about their stock, the manager probably can give you some good advice.
