The standard formulation is that you would only prefer to commit quantum suicide if, if you happen to survive, you’ll be better off by some standard. Overdosing but waking up in the hospital doesn’t count, but gambling your life in interesting ways does.
The reason quantum suicide is attractive when regular suicide isn’t is because MWI gives but there’s still a chance extra emotional weight.
The “only states in which I’m alive matter” utility function will tell you to play Russian Roulette at any odds, so long as the payoff is positive, regardless of whether you believe MWI or not.
And even if you call death utility 0, then it can still be rational to play Russian Roulette, so long as the payoff in utilons is high enough to justify the chance of 0 utility, again whether you believe MWI or not.
