Gandalf ABSOLUTELY give it a try. Read through this thread and look at how many people who have tried it and remark on the pain killing properties.

Seriiously.....what have you got to lose by trying it? A couple grams of ganja?

I remember goiing through pretty much the same "what's the point?" part of depression too. Hang on.....although I know how tiring life can be with depression.

Good luck.
