I've been struggling with sleep. I've been battling complex PTSD and really struggle with certain sounds - they're incredibly triggering to me. I've been using my sleep mask for a week now and am FINALLY able to sleep. I'm not hearing the sounds that disturb me so much and I actually feel a little safer at night. I wish the ear muff part was a little larger (like Bose headphones), but I don't mind tucking my ears in if it means I can sleep. Thank you so, so much for creating a product to help nights be quiet again.
