THE ANSWER TO THE RIDDLE IS ME : A MEMOIR OF AMNESIA
by David Stuart MacLean

Here's an interesting premise. This guy (the author) "wakes up" on a train platform in India having no idea where he is, how he got there, or who the heck he is.
A police officer takes him to a mental hospital where he has these hallucinations. His symptoms are caused by the anti-malarial drug Lariam that he has taken. He goes back to the States to figure out what his life was like before.
Sound intriguing? I thought so,too until I got further with the book. The more I read, the more he disgusted me. David Stuart MacLean is self-destructive. He is taking medication to counteract the effects of Lariam on him, but is drinking an exorbitant amount of alcohol which is not too smart with narcotics. At the same time, MacLean is smoking way too many cigarettes and he is an asthmatic. He writes about these two vices ad nauseam.
MacLean's writing is, at times, very good, but most times irritating. He uses way too many similes to "enhance" his prose. They're definitely not needed. You get the picture the first time you read the sentence. It's just endless filler.
I probably should have stopped reading the book early on but I stuck with it because I wanted to see what happened to him. By the end, I could care less.
Not recommended.
