I've had ideation since childhood and we had no internet back then so... Overdose on paracetamol, jumping off (a not tall enough) building, slashing wrists. I'm glad I didn't try them. As I aged, my ideas became somewhat more realistic- jumping off a cliff or bridge, (warning! NSFW) possibly cutting off my entire hand with a cross cut saw. (No, I don't think I could do it.) When I was prescribed codeine, I hoped that might be better for an overdose. Again though- I'm glad I didn't try those methods!
