Ouch. The first few days on MAOIs was eye-opening: I realized what it was like for 'other people', and realized why I had felt so misunderstood for so long - I was being misunderstood :) Other people had had no reference to my distress, and I had had no reference of life without it.
I tried all the MAOIs, and ended up on EMSAM - it's Selegilene in a patch form. The other (oral) MAOIs caused such profound drop in blood pressure and pulse pressure that I would frequently get the mid-low 'roaring' tinnitus that is evidence of an event causing permanent hearing damage. I also collapsed several times. I'm getting the roaring now from time to time with the EMSAM, but I really don't have any option but to suffer the hearing loss at this point.
(Fyi: doctors - even ENT specialists aren't aware that low blood pressure - even extremly short term, acute episodes - causes hearing damage, despite a significant body of academic literature on the matter.)
I have been taking it in combination with a modest amount of Provigil and caffeine, under my psychiatrists guidance. Caffeine is a much more powerful stimulant when combined with an MAOI. IMHO, it's the combination of the three that is helping me. If I stop taking either of the stimulants, I start feeling worse after a few days. I'm not cured by any means - yet, however I'm better than I have in memory. My SO concurs, too.
(I've been on EMSAM since ~September. I spent the rest of last year going on and off all the others)
IMHO, you may want to try it in combination with other drugs. Stimulants worked for me, but I'm on the ADHD spectrum, which may have something to do with it.
