Umm...you do realize that seroquel has no recreational potential, right? Its an atypical antipsychotic which is classified as an all strong tranquilizer (in a very general sense it work by inhibiting the activity of dopamine, serotonin, and adrenaline, basically a temporary chemical lobotomy).
If you take that tablet, its almost a guarantee you will start feeling very stupid, mentally "blunted", and then fall asleep for 12 hours. There are also more unpleasant side effects if you stay awake, such as light-headness (not the fun kind, the fuck-I'm-going-to-black-out variety) and deleraint-type hallucinations. Snorting or plugging this tablet is an even worse idea then swallowing it,the fewer foreign substances in your sinus or rectum the better.
Save this pill for when your crashing from a stimulant of some kind, and desperately need sleep. It has absolutely no value in any other context.
