Side effects that I noticed was my skin returning to its normal sensitive state. My skin is naturally very sensitive for example I break out in rashes from shaving etc or rubbing off something.
I found that my skin was quite oily, my cuts and things lasted longer than I'd expect and I got less erections which I didn't enjoy I like feeling on edge. I never got any rashes from shaving though, I used to have eczema and actually became less scratchy than ever before. I thought that was very strange indeed.
I've encountered the less erections/arousal for a day or so post MT-2 and would say it is the only side effect I can think of while coming off. Cool topic C!
