2.5 gram trip was weaker than usual?

And my tolerance was low, hadn’t tripped in awhile. Not that it wasn’t good it was just surprisingly weak. No hard come up. Usually it starts off with fear and anxiety. Which is thrilling for me because I know the wilder the come up the more profound the trip ends up being. There was no come up feelings and it was more like a Smokey vivid dream. Usually there’s rigidity to the closed eye visuals and I’m flying. Could it have something to do with me having been really busy the entire day driving hours on end on low amount of sleep then my plan was to just lie down and all night? My work schedule is nocturnal and I was in the process of switching my circadian rythm from day to night. I’m very good at doing this. Probably a bad idea to plan a trip on a circadian rythm switch correct? It was calm and easy though. Compared to usual I get pretty wild CEV and come up at this dose normally.
