The va has a habit of shotgunning multiple drugs at patients, sometimes it irks sometimes it doesn't, if the individual isn't proactive and just accepts what they give when there's problems shit like this ca happen.  There are certain medications in this category that I cannot take because of brain chemistry issues, the make me physcotic instead of happy. The va has a serious case load, and a lot of the docs just go down a list checking blocks, if you know certain mess have certain results for you they don't want to hear it. They put my buddy on serious amounts of Valium for his anxiety, wayyyy to much, he could barely get himself to go to the bathroom when he was fully dosed.     I'm not saying that he was being treated by the va, or was even taking any, but even on this board there are members who were on physcoactive medications who had a bad reaction, I know of one who actually had this happened and it lead to them committing a serious felony, which lost that person their gun rights and caused them to spend time in prison.

The possible drug comment,,,

Up there it could seriously be anything, a good candidate is spice or bath salts, the insane crazy shit people do on those is unbelievable, and can mirror plenty of side effects of things like meth or pop.

The discarded clothing comment,,,,,

Yes, later stages of hypothermia make you feel like you are burning up. It's easy for someone to say that they would know better and not strip down. That's nit the case, what you aren't taking onto account I'd the degradation of your mental capacity in that situation.     I have had hypothermia twice, one you get past the feeling cold stage it's kind of like your brain turns off, impulse control and rational thought kind of take a sideline. There's a good chance that if I hadn't been with other people the first time I would have died, after the part where I thought I would never be warm again, I started to feel hot, that's about where everything gets really hazy and I don't remember much.
