Is the Alexander Technique beneficial to clarinetists?

I often feel stressed and like the whole thing isn't flowing easily when playing pieces that are highly technique-oriented, and I have the option to choose Alexander Technique or Music in Film for an elective class. I've heard the Alexander Technique really helps singers, biologists, flutists, etc. but have never really heard about it doing mug for clarinetists. Is it beneficial for clarinetists to learn?
