I've been tripping about once a week on 2c chemicals, some weeks its twice, others its once in a two week period. this was from Oct 09 to March 1st 2010. I've never done MDMA, but i must say that I have lost a good 40-60% of the "Magic" I got from 2c's.
I love psychedelics so much, so taking any sort of realistic break, one month, 50 days, 3 months, 6 months, is very difficult, because I
the psychedelic world oh so much!
I take vitamins every day
Fish Oil
Vitamin C
Vit B Complex
and a badass Multivitamin called Synergy 3000 (its expensive compared to other multi's, but its got a lot of hard to find shit packed in every serving, otherwise I'd have to spend a good $60 to get like 8-10 different bottles of the stuff that's already conveniently in the Synergy 3000.
I also started taking Piracetam 5 days ago and noticed that helps alot, as I'm a student. Although I have yet to see how/if the Piracetam will hopefully "potentiate" my next trip, so good luck to me i guess.
In short, if you've lost some of that visual/sensory/mental magic from RC's, First:
1. Take a break, at least two weeks, if that doesn't work then wait a month.
2. Eat healthy, that means unprocessed stuff, veggies and fruits are from nature for a reason
3. Starting a daily vitamin regimen is
never a bad idea, so you may want to look into that, (here's a thread i started exactly for that purpose, check out skatardude10's post, words of wisdom...)
But like I've said, i was tripping about once a week (id say 5 times a month) from 10/2009-3/2010 and the magic has kinda gone. So you may want to take a nice big ol break, and then start up again with more time in between (once or twice a month trips) or just gradually trip less and less (that sounds depressing though
)
