A Godsend! I was at the ER on Wednesday night and was told I had a 3mm stone and sent home with pain meds. Went 5 days with on again off again excruciating pain. I ordered this Sunday morning with same day shipping. Took 3 pills when I got it(about 7:30 pm), another 2 pills around midnight, one more around 2 am(couldn’t sleep). Woke up the next morning and took 2 more and by noon I passed my stone. Highly recommend!!!
