legitimate question. see kuntreisi shiurim [Rav Gustman] on bava basra on hezek shechainim, he brings the beis ephraim who says that the issue of hezek shechainim is that of ‘lifnei iver on himself’ meaning, that he is “machshil” his future self in hezek. [apologies for the atrocious spelling. cant do hebrew]
hope this helps
