Thanks for sharing, must've been quite the experience. Take time integrating.

Peace.

I love that so much, you had a truly beautiful experience!

To question 1:
I'm not sure what your dosage is, but if you were happy with the results, I'd say it wasn't too much. From what I've read, it really differs every time you do it, so I would take the same dose you did the first time.

Question 2:
I would definitely say, from what I've heard that DMT sounds so much more awesome than anything else out there, but I feel like after my first trip, I would definitely continue to do acid just because DMT seems like a once in a while thing, and tolerance builds up pretty fast. I'm not sure if I'm answering your question or if I misunderstand, but I feel like spice is the most desirable, by far. I can't wait to have my first trip next week!

question 2 - The synergy between DMT and other psychedelics is incredible. People often use the spice before ingesting another psychedelic in order "clarify" the information received on the trip they're about to embark on. Many also use the spice during or after or any combination of the three. Personally, I love DMT and LSD together. Typically other psychs also make the DMT trip seemingly last longer. When I use the spice at the peak of an LSD trip... well there aren't really words . I've used it with gold caps and MDMA as well, and a combination of all 4 substances at once. What you're experiencing as a flashback was probably just a part of the trip you had that you did not "figure out" or understand until that point in time that you were on your LSD.

I can't find any dosage given, have I truly gone blind this time or have you not mentioned it in the text?

Or is this your "dosage" which you later on doubled?

Tolerance does not build up fast to DMT at all, actually, there is very little tolerance to even be built. I have journeyed multiple times in the same hour.

Wow, from 30 too 75 I'd say is a guaranteed overdoing.
According to erowid and myself; most people need 40-50mg for a breakthrough dose and 55mg+ tend to be too intense for most. So with the latter in mind 75mg is an insanely high dosage, on the other hand I've read A. Shulgins DMT reports and he goes all the way up to 100mg.

Considering A.Shulgin is a veteran with these things and uses a very high quality product one could only phantom what he truly experienced. So there's always too many variables to take in account when reflecting upon these kinds of experiences, especially since your cousin offered you the pipe again, I'd assume he did so because there were still spice left in it?

Hope this helps If I want to get "far out" I go with the 50's in mg's, atm that is
