Due to the nature of this forum, there are a few things that I feel compelled to address first:
1.
NEVER attempt to perform an extraction while intoxicated or altered. There are dangerous elements to this process that require your mindfulness. You already addressed how you feel about this, so to reiterate, I had to make a comment.
2. You need to scale this extraction back. There's not really any need to do an extraction with anything more than 100g of starting material. Large scale like this is a recipe for disaster...
Now, as boogerz stated, don't throw anything away. More often than not things can be remedied.
Evaporate, scrape and re-x. Recrystalization is relatively simple.
To Re-x:
In a small vessel (I use a small glass cup usually) place your DMT to be re-x.
Use 20-50ml of solvent and pour into the glass.
Cover the glass.
Moving the glass away from the stove, bring a pot of water to a boil.
TURN OFF THE HEAT once boiling.
Place the glass in the boiling water.
Remove the lid and stir, allowing all of the actual DMT to dissolve in the solvent and leaving behind any adulterants.
Pipette/decant all of the solvent leaving the adulterants in the glass.
Place new vessel with the solvent in freezer and allow for freeze precipitation.
Pull out of freezer, pour off solvent, allow to dry.
Scrape, weigh (if you're so inclined), gush, and enjoy your goodies.
Depending on your yield and how this goes, we'll also be able to tell if there's anything you need to do with the overall extraction (aside from scaling back).

What if the "truth" is: the "truth" is indescernible/unknowable/nonexistent? Then the closest we get is through being true to and with ourselves.

Question everything... including questioning everything... There's so much I could be wrong about and have no idea...
