Where I live it is hot as fuck. I haven't been sleeping more than an hr or two a night. I figure I will sleep most of today. My knock out puch wil be some codeine & ambien, not huge doeses. Any thing that could be considered a bad idea here?

Rather then risk doing what my friend did (OD on that shit, then shit his pants and pass out, woke up a week later in the hospital with charcoal), try this.

I know its really pussy, but take a shitload of that kavakava/chammomile tea, filter it a lot, let is steep for like 6 hours, and you'll have a shot's worth of this murky brown disgusting shit.

Swig that fucker.

So.
You're planning on sleeping all day today, because you've only slept an hour a night for a while?
The reason you've only slept an hour a night for a while is because of the temperature?

In my opinion, what will end up happening, is if you sleep all day today; you will have an even harder time sleeping next week, when you most need it.
