i just wanted to say, i keep reading people saying that tripping frequently often takes the "magic" out of it.
I respect other peoples opinions and of course you start battling tolerance and being used to the effects, but for me, i cant say I agree that the magic disappears. hell wth good acid, spaced three days apart i could be happy as a clam. tripping doesnt have to be just one thing. I like to trip and work on projects, or trip and really absorb a book i have been dying to read. or trip and watch a great movie.
or trip and go for a walk. or do some writing. get shit done. talk on the phone for hours and hours. whatever. for me it turns me into a worker bee, or a space cadet or strange bird on any old day of the week.
sometimes i take a good break and come back and trip my face off. but sometimes its the more frequent trips, where i have my bearings and its integrated into my daily life, where i make the most connections and have the most life changing insights.
i just love the way my brain works on acid.
visuals are great but i see them more like the sideshow.
although i must say, the first time i threw in 30mg of 2cb with acid, i said, wow, i havent hallucinated like that since i was a kid. and it WAS real nice to just sit back and watch.
but i dont think it loses its magic when its a frequent thing. just a different kind of magic.
so in answer to the question
if you want more visuals, wait. or take more. or get into a really paranoia inducing situation

... but seriously set and setting can really help get rid of tolerance. go out of town or something.
but you might also want to step back and think about what exactly you expect out of tripping. are you doing it just for the visuals? or for the way music sounds?
what good things is it teaching you? and are there any negative effects? and consider whether or not you always need to have mind-blowing experiences with it.
i think you said this is your first year or two of tripping?
it might sound corny to some but I wish i had kept better journals of my first few years tripping....to see the changes that were taking place in me, and so I could look back and laugh at some of the trip reports. it can be hard to remember all of that 20yrs down the road.
some people click with psychedelics on a level where they like to immerse their lives in them constantly. I havent met too many in the real world, but I see their posts on here and it makes me smile.
others like to just come back a few times a year or once a month.
whatever works.
and a fun thing to do while you ARENT tripping can be to do a bit of reading up on the history, etc....ACID DREAMS (great book) etc.
also....i know that for me, in my first year or two or three of tripping, a lot of things about me were changing very fast. i actually took a year off to take stock of who i was becoming and what the permanent changes were going to be.
i am rambling and i dont know if any of this makes any sense.
anyway...good luck with whatever you decide to do.
