DMT was my first psychedelic experience. There are some advantages to a small to medium dose:

1.Very short

2.Breaks through the anxiety barrier quickly

3.Powerful to show you whats possible with psychedelics

Mushrooms can be very emotional and i think more challenging than a sub breakthrough dose. With dmt, there is no room for negative thought spirals to occur - youll be too amazed for that.

After your first experience, a seed will be planted. You don't know into what this seed will grow, but it will be planted. You will gain knowledge, but perhaps not the knowledge you are expecting.

A common theme is to think the following: "WTF WAS THAT?"

Its especially mindblowing the first times because you have absolutely no clue what its about.

But thats ok, because noone really knows...we are all learning, developing. Smoked freebase can give you that one kick into the realms of the psychedelic. It can...no IT WILL fill you with wonder and awe, leaving you re-structured and possibly intrigued. For me, the days after my first experiences were all about discovering new subtletys in life....

In general, you can learn more about "yourself" with ayahuasca, in terms of clearer messages...but ayahuasca is a whole different animal. If you are curios..freebase is a good option. But: Don't forget that this is no childs play. It demands respect, responsibility and you have to !!!!listen!!!!. They love you by loving you, they love you by punishing you..

Beside all that, you seem to be a good candidate, judging from your post only.

But only you can decide, and only you should decide.
