De Lune for period pain has been really impactful on my life. I have struggled with debilitating cramping that's sometimes accompanied by fainting that has me canceling a day of my life every month. For context, I've also had many kidney stones, and sometimes the cramps wreck my day in the same way. De Lune has really cut back on that pain in a way nothing else has, and combined with Tylenol has me living mostly normally with perhaps a couple hours of downtime at its worst.
If you're using it for a couple days, it's basically a whole pack a month. I wish there was a subscription option that was at a slightly lower cost.
