I've been experimenting a bit with this one over the last year.
While I've found it to be hardly noticeable orally, smoking it makes for a nice buzz somewhere between a cannabis high and a mild trip with gentle breathing visuals and a nice headspace.
Not very functional socially, but very nice for total immersion in a movie for example.
And as I've seen others mention, the munchies one can get from 5-MeO-DALT are indeed completely ridiculous

My smoked doses have been from 10-30mgs rolled up with tobacco.
However, the only time I've combined it with another psychedelic was at the tail end of a quite mild 2C-D trip, and that blew me away.
Me, my girlfriend and a friend had done ~40 mgs of 2C-D, had a real nice evening with lots of laughs and just talking and having a good time,
and when the effects started going away I suggested we share a little bit of 5-MeO-DALT to keep the magic going just a little longer.
The others agreed, and I rolled up 25 mgs that the three of us smoked.
Felt very good, just like it brought back the trip a little bit, until 15 minutes later...
BAM! Melting, morphing, cartoony, rubbery visuals everywhere, and it brought on an unexpected amount of anxiety.
I noticed that my girlfriend looked uneasy too, and when I asked her she just said that something wasn't right.
I got her to describe what was happening, and I understood she had one of those trips where the body sort of disappears and everything dissolves.
I had experienced similar things on previous trips(on other substances) and was able to talk her through it and keep her grounded.
She has a bit of experience in psychedelics, but she hadn't been to that point before.
If we had pushed it to that point on purpose she'd probably not have been that scared of it.
Our other friend seemed to only have a good time though, but he's definitely less sensitive to all substances than us.
So anyway, I just thought I'd share this just so people know that it can really synergise a lot more than you expec with other drugs.
Oh, and another tip; if anyone else gets that horribly dry mouth that won't go away when doing this, a little chocolate is your best friend
