is it ok to mix rum and whiskey ?!

I have done that. Ive mixed the two then added some coke.

Try a small amount to see whether you like it. There is a drink called a rumba, 1/3 gin and 2/3 rum. Not too bad. But wicked.

no definitely not, my grandad died by mixing the two together, WOULD NOT ADVISE!

WHY? No

well nothing happened to me i drank a while bottle of both of them mixed

I've done that!
It's best with Vanilla Coke. :))

Yes I've tried it.

mix them together, drink like a man!
