I started taking this around Labor Day, a spoonful or three here or there when I could remember. Sometimes I'll mix it up with hummus, crack some pepper on it and eat oily hummus with carrots. It's also good on pizza crust and in guacamole.
Anyways, my experience matches up with a lot of folks:
Weird, very vivid dreams the first few nights and after larger doses. Ordinarily I hardly remember my dreams at all.
More energy, need for less sleep. After about 3 days, I had to pull an all-nighter at work and stay up until 6am (and get back in before 10). It sucked, for sure, but a lot less than it usually does. It basically felt like I had been up for 3-4 fewer hours than I had been - much less of a "fuck this, I don't even care about these stupid documents, I hate this, it's way too late, I'm exhausted, when can I go home" and more like, well, this is late and I'm getting pretty tired.
Gym performance got a bit better - I don't do much cardio since I'm easily bored, but I found myself doing a few extra reps on most exercises and didn't feel quite as beat after 7-8 different 3x10 kind of sets, did a few extra exercises. I seemed to have a correspondingly bigger appetite and found myself eating more. I haven't really kept it up (but mean to get back). I also did Bikram Yoga for a couple weeks, for several days each week - I was pretty impressed with myself, and much better able to withstand the heat when coming back from a break than I normally am.
My skin is definitely softer and a bit oily - kind of nice, really, since I went on accutane in my early 20s and NY winters are pretty dry. My hair is relatively happy, too.
Other stuff I feel like I notice that I might be making up: things look a little brighter/colors look more vibrant, I feel a little down/cranky if I go 4 days or so without a dose - it seems to normalize after a few more days (I'm not following any kind of precise regimen) and a bit cheerier (maybe because I sleep better?) when I'm 'on', complete relief of joint (for me, shoulder, especially if lifting) and lower back pain (it's not usually bad but sometimes flares up a bit).
Had a couple of unfortunate episodes with alcohol. I seem to have a higher tolerance, but then up my consumption, and wind up feeling like total garbage the whole next day and/or puking my guts out (which is quite rare for me now that I'm in my mid 30s).
Anyways, that's really all I got. I like this stuff and will probably keep it up. The needing less sleep/feeling rested on less sleep is undoubtedly the best part (I work a lot), but the skin/hair stuff is nice too. Hopefully it doesn't make me go blind with cancer or whatever.
