I've never had a problem with MAOI contra-indications, or interactions with other things.  I take Zoloft (an SSRI), and have even taken it hours before an MAOI with little or no negative effects.  Now i'm not suggesting anyone do this, because what works for me, might not for you, but i don't think it's as serious as you might be had to believe.    However, one time on acid i ate a whole bunch of aged cheese in some lasagna. I had to make myself puke the stomach pain was so severe.  So, go figure.
