It's a miracle. I used a packet when it arrived, and a packet before I went to bed. Last night I had my first good sleep in over a year....I rarely get a restful nights sleep. Last Night I Rested! All night I slept and rested. I felt like a new person today, and it's only getting better. Thank you and you'll be hearing more from me and my hubby, he's using it on the tendons of his hands.
