i have!!! after my mom passed away i could not sleep at all. i would literally stay awake for 4 days at a time, crash for about 3 hours, and then be up for another 2-3 days and then repeat the cycle all over again, it was miserable. i tried a ton of natural meds and stuff like melatonin, but it didn’t do me any good. i’ve been on prescription sleeping pills for about a year and a half now, and while they’ve done so many great things for me, i absolutely can not fall asleep without them now, and that really sucks. talk to a counselor or a doctor and see what they can recommend for your situation.
