Harmalas, and Lemon Balm tea (3 to 4.5 grams of dried leaf made into a tea). That was my go to. Lemon Balm inhibits GABA Transaminase and raises GABA levels, which relieves the anxiety, come up intensity, and bodyload, at least for oral DMT, should do similarly for smoked/vaped DMT. Harmalas can contribute because they can allow you to smoke/vape the DMT at a gentler pace, what i like to do is pack a bowl of Changa, or take some Harmalas orally (but i also like to smoke Harmalas because i feel like smoked Harmalas potentiate the DMT more compared to oral Harmalas) and then i'll smoke on the DMT kinda like you would Cannabis pretty much, you just smoke/vape it at your own pace and work your way into it. Basically, if you take a few hits and allow the initial DMT come up intensity to rise and then stabilize, after that you can smoke/vape on the DMT and it's as smooth as a hot knife through butter. As long as you get that initial intensity wave out of the way, from then on it's smooth sailing, and also doesn't require you to smoke/vape as much DMT as you can within a minute or what not, it's a much gentler pace in comparison. Similarly, with oral DMT one can sip on the liquid DMT/DMT-containing plant tea for approx 10 minutes for a much smoother come up, you can add Lemon Balm tea to the mix for some extra smoothness if desired.
