I LOVE vicodin, but I only take it for 3 days straight about every 2 months, and here's why:
1.) You'll get hooked after about 3-4 weeks of taking it every day. After that, it's the same as kicking a heroin habit - good luck with that.
2.) After a few days you build a tolerance, and you have to take more and more to get the same buzz. I know a guy that takes about 30 a day to get the same buzz I get from taking 1.
3.) The tylenol royally fvcks up your liver. Good luck picking up chicks when your liver fails and your skin turns yellow. The same guy I know that takes 30 a day has almost complete liver failure. Of course that doesn't stop him from eating them like candy. If you're into it for the buzz, ask your doc for a drug called norco, that has more codeine and less tylenol.
4.) It hurts your sexual performance. I can't personally get off when I take them, so I time them around the wife's period. If you randomly hook up when you're high, you'll give the chick a complex when you can't cvm, and if you can't cvm, what's the point.
5.) It's a crutch. The best way to sarge is sober. Also, I've found it's easier to dodge a pool stick when you're sober, and chatting up some guy's girlfriend at the local pub.
6.) It'll turn you into a criminal if you become an addict. I know a couple peeps that have done jail time because they forged prescriptions. Most pharmacies cross reference their databases and it kicks out a red flag if you buy them all over town.
Better living through chemistry as I always say - just be smart, and be informed.
