I'm kinda with Cpt.Crispy on that. In the middle, I'll be doing 4 - 5 a day, then about a month and a half later, it will go to just 2 a day, then I'll find that Ive slept through entire night with absolutely nothing, and they're gone. It's usually about 1.5 months for me. But I did notice that if I drink a lot of Ginger Ale, it seems to help keep the attacks at a lower number. And I've also noticed that staying away from tap water helps too! Ya never know what might be in that water that can cause an attack!
