Specifically a potassium sparing diuretic which means it will cause you to crave salts but let the potassium salts build up. Be particularly careful with potassium rich foods.
On another note, was that thing with the jalapeños something you would have done prior to spiro? Several of us, myself included, went through periods of craving really spicy foods. I tended to put as much as a 1/4 teaspoonful of ghost pepper sauce in two scrambled eggs. I still can, and do, but I don't crave it anymore. Not absolutely sure it was the spiro and not the estradiol, but it went away after my PCP took me off of another blood pressure med since I was also taking spiro and the combination dropped my BP too much.
