If there was a method of committing suicide that was completely painless, do you think more would attempt?
For example....a simple pill you take and once you fall asleep you die. No pain, no awareness, no chance for "side effects", etc. You just take the pill and that's it.
barbiturates can do that easily, there's like dozens of celebrities that died from it in the 20's, 30's and 40's. really easy to OD especially if you mix em with alcohol and other downers.
but to answer the thread, who hasn't thought of suicide? honestly i think your life is more fucked up if you haven't. those of us that have been there usually end up never doing it, the option of doing it is always there but once you've been at that stage it's like "fuck it, why bother". it's always some upstanding white collar "normal" family man with 3 kids and wife that thinks "oh those people are not sane" and then ends up snapping and killing his family and self when he can't afford the payments on his 3rd mortgage.
