I began with 5 drops this morning. I will take 5 more drops early afternoon. I know 15 drops is the beginning dose, however I can never take full amounts because I am very petite. I do not want to take any too close to bedtime for now. I will gradually up my dose to 15 drops as long as it doesn't interfere with sleep. I am sorry it took me so long to start but hopefully I will have good information to share next Sunday
