Human beings do require sleep, yes indeed!

Sleep deprivation in extreme cases can cause hallucinations, so it's always better to sleep if you can.

I've taken trazodone actually... I didn't particularly like it. I've also taken Gravol to knock me out and it basically had the same effect - I got dizzy and droopy and then passed out. Not pleasant!

The problem with sleep meds is that they can wreak havoc on your system and can make you more tired than anything else. Also if you oversleep you wind up feeling tired - so trying to sleep 6-10 hours is preferable if you can manage it. Once your body becomes accustomed to a certain level of meds (dosage), then it requires more to have the same effect. So if you're having trouble sleeping, can you talk to your doctor and maybe see a sleep specialist for tips that aren't med related?

Also - did you do the med increase by yourself, or with a doctors recommendation?
