GBL and Psychedelics

I usually find the comeup on acid uncomfortable and found out that taking a little GBL works like a magic potion. As the runtime for GBL is just about an hour you can take it like a mini trip killer without ruining the whole experience. When u take just a little bit it can change the trip into are more positive experience. But be careful and know you‘re dose u don’t wanna die. Can anybody say the same about mixing these substances? I didn‘t see much posted about this kinda thing on this sub and wanted to share my experience. (Sorry for grammar)
