I would not advise using DMT. I understand there is a peak to be reached, one way beyond sober human imagination and I enjoy every bit of the majestic psychedelic experience, but if I had access to DMT I'd try to 'restrain' myself to having super-short normal-strength trips. I would never go into a full-blown DMT trip. I have heard several people mention their depression vanishing but their anxiety going way high. Both can be devastating, of course.
Although I wouldn't do it myself at anything other than a laughable dose, I can only try to imagine what the DMT universe is like at
any dose. Don't think there aren't any risks, because there are. Many. Having said that, have fun... the emotions you experience on a DMT trip are orders of magnitude beyond any other.
Oh and I wouldn't use it to 'balance your brain.'
Sure it can make you feel 'positive' for a while, or 'negative,' but you are modifying your brain in a really crude way (although DMT must seem amazingly clean and I am telling you, face to face, it is a drug like any other, tryptamines such as LSD, phenethylamines such as mescaline, alcohol such as alcohol. They damage the brain in very unique ways, but they all have their own share in the damage they cause. Death of brain cells is just a small part of brain damage. While the people here may tell you nothing bad will happen and your brain will be normal within a few weeks, I would count my prayers if I came out feeling ok. I really wouldn't take more than a regular tripping amount, as a few minutes of more 'normal' tripping would be fun yet pretty safe. Organic brain damage doesn't equal actual brain damage... I'm not saying don't do it but fuck a lot of bluelighters think it's safe or good for you, and it isn't (I won't reply to replies to this comment, unless it's from OP).
If your trip(s) turn out to be good, you'll probably laugh at this comment... it's not addictive but it still has ways to suck you into its world...

Don't laugh at this... one day, you may have a bad trip. Know what that means? I hope so.
Peace and love, have good trip!
Good luck man!
