I took an MAOI for a bit, not long ago. It basically functioned like taking a little bit of amphetamines every day. It would give me more energy for several hours after taking it. However, there was a side effect: very very high heart rate (~120 resting). This is because the drug I went on, Parnate, is chemically similar to amphetamines. My blood pressure and heart rate are normally both very low so this was definitely biological. I think there are other MAOIs that are not so intense, but I chose this one because it is supposedly easier on one's liver than the other choices.

Final verdict: I would try it if you are desperate and have tried everything else. It didn't solve my issues but it did give me the energy boost to try. As for the side effects, no harm no foul- they go away if you stop taking the drug.

Good luck and hope things improve for you soon!
