The best I have ever been (besides now) is when I was on
Seroquel. The lesson
to learn is
to not fight the
sleep. You will wake up tomorrow and have another day. You will not lose that creativity if you go ahead and go to sleep and if you wake up early in the morning, take a shower and draw, write, or meditate.... once the grogginess goes away. And it will.
Use this information, experiment if you must, but like crystal said, advocate for yourself.
