Yes, but I would caution to do it prepared that you may lose executive control and die.
I've tried it out many times with that attitude, and I would have been fine if I'd lost consciousness, gone into the convulsions, and died, no regrets.
If it's not the right location or time and you don't want someone to find your body who would, then it's not a good idea. If there are things you'll regret not having in order first, then it's not a good idea to test until those things are in order.
Just my perspective.
