There are a couple things that have really helped me.
One is to remember drinks which are a variation of another for example Long
Island to Long Beach to Sweet Jesus Walking on Water. If you can remember the
basic ingredients naturally, then all you have to recall is the mixers or
additional alcohols.
Another thing is to look for key words in the name.
Wall = Galliano
Slow = Sloe Gin
Comfortable = Southern Comfort
and etc.
