I just think back to nights and mornings kneeling by with my head in the same place I put my axx. Gross. The severe headache and acid reflux and the $350 I have to shell out because I fell flat on my face and busted my glasses. Good Times!! I think not. Maybe there are people who can have 1 or 2 and quit but that's not me. Just get through the night. You'll be so glad.
