If your asking re:which opiates then you might not have much luck as most of them or anything else that laters in anyway the central nervous system is going to have a direct bearing on how well you regulate body temp,also talking about the lyrica,halcion,of which I have not seen used in many of years,and the anti-d's as in the wellbutrin. Sorry that isnt much help or the news you needed to hear but it is an example of how we have to change our lives to the point of misery to achieve any kind of relief sometimes.
As for the direct sunlight warnings and which are better then others your RPH can give some tips concerning that but I get the feeling alot of what your referring to is the sensations of just being or feeling hotter then the other folks in the same room and again this is anything that is going to directly effect the brain and its functioning and that certainly includes the center that regulates body temps and sensation and there isnt much help for that without eliminating all those kinds of meds and that doesnt look as if it is a possibility for you.
Sorry for not being much help here but this is the way I am reading it and what I know. Others may have some more tips or advice that can help you.
Good luck to you.
