No. If I am NATURALLY high, I will stay up really late, and I have done that lately. But I WON'T take a bunch of caffeine at night and artificially push myself into an unhealthy state of mind. I only drink a moderate amount of caffeine during the day. Also, I try to get at least 6 hours of sleep/night if possible, because I know all too well what can happen if I don't. I also take my meds religiously as soon as I wake up every morning.
However, am I high? OH YEAH!

Am I manic? You better believe it!
My point is, if you are feeling high, it is better to try your best to stay stable and enjoy your high, rather than push yourself into a dangerous frenzy using stimulants!
