Sizzurp puts errything in slo mo. Mixes well with cigarettes too.
Why do you need a prescription... you can easily cop that shit in any ghetto area.
If you are super dependent on getting a prescription, you're gonna need to get a cold (really no way to fake that to a doctor), and then you tell your doctor that your coughs are keeping you awake all night, and you can no longer take any more sick days at work and YOU NEED TO SLEEP. That should get you a bottle pretty quick.
