So, given all the JDtic rage and whatnot, I jumped on the kappa-antagonist bandwagon and decided to test a combination of buprenorphine and low-dose naltrexone (based on celebes recommendation).
I was using the 8mg strips, which are kinda hard to cut and dose, given the propensity for the pieces to just vanish in your mouth occasionally. But I would typically dissolve between 0.125 and 0.45mg under my tongue, and then take a shot of 5-10mg of LDN. The LDN kicks in after about an hour, and the buprenorphine 90 minutes later.
Buprenorphine alone just made me puke for about 24 hours. If I got the ratio wrong and combined too much buprenorphine with LDN, I'd feel foggy but calm and sedate. Now, given my baseline of akathisia and terrible sympathetic activation, I'm sure my experience is very skewed -- but overall, I found the kappa-antagonist experience to be slightly disappointing.
The most prominent changes were:
A clearer head.
More physical energy.
Less pain.
Better focus.
Socially, I was able to look others in the eye with far more ease; my sense of humor was also a little better.
I know all that stuff is technically a plus. However, it did almost nothing for my awful phobic avoidance and OCD, aside from clearing my head a little. There wasn't much reduced fear. I was still cripplingly fearful of very irrational things. And I also didn't feel much of a restoration of my inner life and emotions -- love, warmth, associations, sensations etc. In fact, it increased my irritability. Overall, the experience was comparable to a low-dose of Dexedrine ..
I tried it 4 days in a row, stopping because I was scared of a rebound effect. Withdrawal symptoms have included increased pain/fatigue and anhedonia. Only other thing I'm taking is resistant starch and melatonin at night.
Like I say, my conditions are atypical and dosing was also off at times, so who knows.
