Thanks for all the replies guys! I'm glad this discussion may have helped some find solutions and different options - sometimes just knowing that the options are there is a relief. I know I wish I knew before...
Looking back on how this relatively minor condition (essential tremors) has had a negative impact of my life ever since I was a kid (I used to make drawing for other kids - they almost always ended up making a remark on my ever shaking hands even though it had zero impact on my abilities) and into my adult life (the first dinner with the in-laws was always a source of worry, especially if there was soup on the menu), and then, obviously, live performance, it was always on the back of my mind.
Actually, up until I was 36 or 37, I never knew what was wrong with me - I figured it was some kind of odd, unique handicap. I never talked about, never acknowledged it - I just tried to ignore and avoid it.
It can also be difficult to project self-confidence when your hands are constantly trembling - at least that's how I felt, not matter how sure of myself I could be in a given situation.
Being a guitar player, there are also some things which can be harder - playing that intro to Diary of a Madman for example... Your wrist gets into that very uncomfortable position for the last few chords, and your fingers all stretched - the tension in the wrist sometimes end up creating some kind of shock wave. No fun.
Anyway, back on topic - if like me you've tried a variety of approaches and find yourself realizing that none really work for you, or if you suffer from a weird bug like me, there are options.
You know what's the oddest thing? From as far as I can remember going all the way up through when I was 11 or 12, I would have done anything to be onstage: lip synch contests, imitations, choir - I'd even write little plays and force my friends to perform with me. Every chance I got, I was up on stage. How we change, uh?
