Actually, its funny that I just saw Ted's post....as I was just about to
make a post of my own concerning a harmala + psilocybin trip I took last
night.
 
I began by crushing up 2.5 grams of harmala seeds, and swallowing them -
qui]it{ a disgusting taste... I waited about 30-45 minutes for them to
digest (and to see if i would throw up) before eating my shrooms. I felt a
slight queasiness in my stomach, but not desire to yack, so I ate the
shrooms (about 30{45 mins after the harmala, like I said).
After eating 1.5g of shrooms (from a previous trip out of the same bag, i
knew them to be quitt({ potent shrooms), the trip began abo{t 20 minutes
after taking them. It came on more gradually than a pure shroom trip. The
trip itself was different than just plain shrooms. Its not really a
describably difference...it seems to open a different (but similar) door
in the mind. Physically, it felt different to. For example, although it
was about 70 degrees outside, it felt to be about 40 d{grees.... When I
walked, I felt somewhat drunk - I wasn't stumbling, my coordinatio{ seemed
fine...but there was that same sense of vertigo that you feel when walking
around drunk.{
Hallucinations were quite different. I remember looking at Venus and not
being able to decide if it was a star or a plane, because it kept moving.
Inside, colors seemed different, but not in the intense way caused by
plain shrooms - they seemed somewhat eartier, and I found myself attracted
to browns, greys, black, and dark reds - quite different from the
attraction to bright colors caused by pure psilocybin.
As{far as MAO inhibition... I was drinking cocacola all night (caffeine)
and ate a cheeseburger at mcdonalds (cheese & meat), but felt no{side
effects...h{wev{r, I do not recommend {ating alot of{ no-n{ foods,{because
althouh s{all quantities can be OK, chowing down on cheeses and alcohol or
yeast or meats could cause problems. Keep it simple, if you decide to trip
with harmala. (You probably wont feel very hungry anyways).
About halfway through the trip, i ate another gram of harmala, to prolong
the trip. It did seem to work...as the trip lasted about 6 hours total
(other trips from the same bag of shrooms, but with no harmala, lasted
only 3-4 hours). The come-down was very very slow, and the peak was quite
long as well. 
My thought-patterns were also{different than they usually are while on
shrooms or LSD. But like I said, th{ differences are very hard to
describe...they are subtle, but they add up to produce a quite distinct trip.
For one, it seemed like a less "freaky" trip. It was very intense, but
there was no sense of panic at all. I would probably feel OK going out to
dinner with my parents while being on this combination - the harmala
really seemed to add a calming aspect to the trip. It also seemed to be
less personal of a trip. Rather than a dive into the subconscious mind (as
with LSD/shrooms), it seemed to be a dive {nto what Jung called the
super-conscious Mind - th{ mind of humanity as{a whole. xDt(Alot of the
things I usually end up thinking of while tripping never crossed my
mind...and alot of things I have never thought about while tripping were
quite prominent in my mind last night.
Harmala is quite legal, and quite easy to get through various mail-order
botanical companies...I highly recomme{d anyone who i]uses shrooms or DMT
try mixing some harmala with the shrooms/DMT. It's incredible - like
tripping for the first time. And I like the doors that it opened in my
mind. I feel like this trip did a lot of good for me.
