My favorite drug? A couple shots of bar rail vodka. If you need to make it taste like something, a bloody Mary or a tonic and vodka were all I needed.
I avoid anything I don't absolutely need anymore. I'm not anti-drug, I simply am, like you, hypersensitive.
If you do need some kind of chemical help, I've tried Sublinox, which puts me to sleep, and if somebody wakes me, it allows me to spring into action within a few minutes.
