It's been a long week and a while since I've gotten a good nights sleep and I've got to keep waking up at 6 am for at least another week. I'd like to take some xanax tomorrow, smoke a little weed and chill out, and hopefully get 10-12 hours of sleep. But I want to make sure I'm able to get up and function at work the next day. I have pretty much an unlimited supply. How much do you know I should take? I have a pretty fast metabolism and I'm a 140 lb female.
