Only reason I've been on the edge about the other MAOIs is because I read this log on Erowids.
"My hearing decreased and everything sounded distorted, as if through a fan. I had difficulty swallowing, tachycardia, and severe anxiety and insomnia. I also had pins and needles in my arms and legs in spite of what seemed like good circulation (my extremities were not pale or cold), as well as brief periods of numbness. My heart rate stood about 110 for five days (my resting H.R. is normally about 62). My blood pressure (which I took many times) remained within normal limits the whole time (both the first five days and during the troubling symptoms). I had brief periods when I felt faint and had difficulty following conversations. I noticed that alcohol seemed to offer some relief, at least from the anxiety.
After 5 days of these symptoms, they largely subsided. My hands continued to overshoot their targets occasionally, the leg spasms in bed continued, and I occasionally had pins and needles in my arms and legs for about six months. I remained on the Emsam throughout the entire time."
Physc that looks very interesting! I'll look up a little more on it. On a side note I'm not completely fixed on having to get this type of supplement. I just noticed this while doing some research for different herbs and nootropics.
