One experiment might be to see how pre-treating a rat with a 5-HT7 antagonist (vortioxetine) changes the way the rat reacts to Effexor. If vortioxetine upregulates 5-HT7 receptors after prolonged exposure, will introducing Effexor afterwards produce more anxiety or less anxiety compared to Effexor alone?

Yes.

Pramipexole was the only drug I tried that was anti-anhedonic -- I got my sense of reward back. However, it apparently desensitised my dopamine D3/D2 receptors, so that the same drug would no longer work, despite a period of wash-out.

Sulpiride yielded a powerful (more so than methylphenidate) "motivational" stimulant effect at first, but apparently desensitised my dopamine autoreceptors, so that the same drug would no longer make a difference. Then I used selegiline for a while and some of the initial effects of sulpiride came back -- maybe selegiline re-sensitised the autoreceptors.

Reboxetine changed my brain permanently, so that I became more depersonalised-derealised -- my emotions were numbed, so that experiences that used to bring me to tears would no longer touch me. It was a welcome effect at the time, but now I wonder what my life would have been without it.
