Potassium salt as a method?

[TVtrays]

I'm on spironolactone, which is potassium sparing, which means, i have elevated potassium levels already. Would causing hyperkalemia be a feasible method?
I know it would be slow and probably not pleasant but the thought of sudden ctb just scares me.

Possible, but inexact. Would result in very painful heart attack, eventually, probably.
