You're actually not supposed to take it for more than a week straight. Its supposed to help you build a sleep routine. You definitely need time off there. PLUS FUCKING 1 I actually had this at the Dr.'s office today. An internist at UM. I was there because of the flu, and the Gardasil shot, so I asked him for a recommendation for Urology. This is word for word how the conversation went: Doc - why? me - well, I'd like to get a vasectomy. Doc - why? me - well, I don't want to spread my genetically defective seed around. it would be wrong for the planet. Doc - do you already have kids? me - does it sound like I do? Doc - well, they probably won't want to do it? me - why? Doc - well, because people tend to change their minds about these things. me - seriously? did you not just listen to a word I said?
