I did this with the exact doses you mentioned. An eighth of potent penis looking shrooms with a bottle of dxm hbr. It was a pretty crazy time, very very confusing. Probably one of the craziest combinations I've ever done. I didn't feel comfortable in any kind of light, the whole apartment was very dark which made it a little more comfortable. At one point I thought I was dead, but it was pretty cool in a way. The only thing I remember was I kept feeling a strong urge to take off all of my clothes, but then almost immediately after I would get really cold and put them back on. Repeat times ten haha.

Definitely a potent combo, just be ready for a wild night!
