Same here. 35 my first time with a GVG. One hit and I was gone. The only difference is mine only lasted about 3 to 4 minutes. I do recall being guided back into my body by an entity while he explained to me that I was a human being  and this was my reality. It was utterly bizarre. I have yet to breakthrough again, as I'm trying to fine tune the dosage. I think 30 might be the sweet spot. I think I will try tonight
