Well I've definitely become more in tune with what all the effects the drugs have are. So there are more effects I notice now, which does make it so even lower (well ok medium 'cause I never dose low) doses seem more "full" than they did at first. My early trips had the strongest body highs, and lots of thought loops/nonsense...but the visuals were inconsistent at first, there'd be nothing for a while then something totally insane, and I didn't know the psychedelic headspace as well so simply didn't realize how hard I was really tripping. Now when I'm tripping I'm having a certain amount of visuals the entire time, and I've gained a lot of control over my mindset while tripping, I can avoid thought loops, not let myself fall into bad thought patterns pretty easily (actually never had any bad times early on though), and I know the headspace now so I'm aware of everything that's happening, and able to maintain clear-headed lucidity even on very strong doses- so basically, I can have a full trip more easily than when I was younger, but at the same time can hold it together even on strong doses now.
