You have great taste in drugs lol, 4 of my favorite right there.
IME, rolling twice in one weekend back to back or with a day in between is fine. I always take 100mg and the second roll is never diminished. My personal rule for MDMA is never more than 12 times in a year (12 x 100mg), and never more than twice in one month. Although, I don't believe I've actually taken MDMA 12 times in a year, I believe 7 or 8 is the most times I've rolled in 1 year). Everyone's different, but I've never had a comedown and 100mg works just as well as it did 9 years ago.
For a 4 day festival, I'd probably take LSD+MDMA two of the days, 2C-B one of the days, and probably take it easy one of the days that I'm not super excited about the artists that are playing, otherwise take 2C-B again.
Was actually thinking about writing a "survival" guide for festivals; substance regimen that works for me, what to avoid, etiquette, etc.
Couple tips off the top of my head I've learned from experience and watching others over the years:
- Avoid drugs like coke, speed, GHB, alcohol and ketamine to a lesser extent. Just my opinion, but these will slow you down in the long run.
- If the festival has good food, bite the bullet and just buy food there. You will have less stuff to pack, create less garbage, more time to rest not preparing food, you'll eat better & more complete meals. This also supports the vendors and festival. It's really not that much more money
- Plan, but don't over plan, your consumption for the week(end). Your body can only take so much and you want to make the most of your time there.
- Nibbling one "notch" off of a Xanax or similar can get you a solid 8+ hours of sleep whenever is convenient (Caution though, just a tiny bit goes a long way when you're on the very tail end of LSD).
- If the festival offers drug testing services, use them.
