I used it for a month and got up to 15 drops one time a day. You are supposed to do 15 drops 2 times a day. You have to take it slow...adding maybe a drop a week. When I got up to 15 drops the die off symptoms made me have bad D and I felt light headed and dizzy. I had to stop because I couldn't go to work in tha condition. I think it would be great if you are at home and don't have to work. I have read the MMS forum and many people have had success with it. There is a 6 drop a day maintenance dose. I'm currently taking dewormer and zapping.
