Yes, avoid the sweet drinks, they will mess you up!
Now, I have found drinking like crown or hennessey on the rocks with "wateredback" does not affect me at all.
But those, Tom Collilns, Amareto sour/Amareto and Pineapple juice, etc. would kick my butt. I stay away from 'em. NOW!
I don't drink as much. Now, I'm more of a sociable drinker.
