I honestly have a hard time with scotch any more, especially single malts.
Years ago, when I was still in the Army, I would down a bottle of Laphroaig on the weekend as a warmup before hitting other stuff.
I puked a lot. Mistakes were made.
I managed to take single malts, which I loved, and destroyed the taste for myself.
I'm currently like 50/50 on them, but after 2-3 drinks that old feeling of my body revolting on me starts coming back.
