some of my own things, ime, that i've learned over the years:
-exercise; that alone transforms you on so many levels, typically for the better.
-healthy food - locally grown produce, locally raised meat. lots of water. the occasional couple glasses of juice from the juicer. even just cleaning up your diet to a reasonable degree and not going full throttle into buying all organic/locally grown/etc/et can do wonders.
-yoga - this has a strong cumulative effect over time - maintaining tendon flexibility, great bloodflow, great gland functioning. also has a relatively strong, cumulative effect on bringing the every day chatter of the mind to a minimal which ime translates into your everyday activities.
-pranayama/breathwork - alernate nostril breathing, learning to focus on the breath and slow to the amount to 2-3/minute, very powerful/beneficial, especially when combined with meditation/yoga - especially yoga.
-meditation - just simple breath meditation, eyes closed, hour a day, or even every other day, affords leaps and bounds in terms of learning to directly embrace and pay no mind to any and all thoughts that come up in your day to day. this takes time, but out of all these departments, meditation has afforded me deep application with the DMT experience.
All these things are just a few categories, but it sounds like your doing well as of now.

I consider the DMT experience a jumping off point, every time we imbibe, we're jumping off from that specific point in our lives; in our evolution, on every level - from physical health and wellbeing to mental, spiritual, etc. It's a direct mirror to the deepest recesses of Self, which is inextricably linked/enmeshed with phenomenal world.
