Your receptors and serotonin stores (vesicles) are certainly working just fine, they are recycled all the time so no need to worry about permanent effects on them.
It could be that disruption of the histamine wakefulness projection has allowed some maladaptive synapses to atrophy. It could also be that at your dose Mirtazapine is starting to block 5HT2A and other serotonin receptors, or that another effect like that is starting to kick in. Please note that 5HT2A is not a particularly beneficial serotonin receptor, you really don't want too much 5HT2A activation - same with 5HT2C.
Another option is just that there was some synaptic reorganization with your night of good sleep.
I would try to meditate. Practice mindfulness everyday and see how things go. The headspace app I highly recommend.
Thank you for your in depth technical insight, Yankinov. I am very grateful for your expertise.
Although I can't quite comprehend some of these terms, I will do some research and see if I can take anything from your analysis as I have little knowledge of biology or pharmacology.
I'll see how I go over the next few days and report back if you don't mind, I could use a guide right now.
I do meditate using the Vipassana method, which helps me accept certain symptoms and reduce my suffering however if I can rid them altogether with such a little dose of Mirtazapine then it seems redundant.
I have been utterly messed up -chronically- *feeling* as if brain damaged; [in order of severity] DP/DR, anhedonia, TMJ, insomnia, depression, ego dysfunction/difficulty relating to others in social contexts.
Despite my best efforts of healthy eating, regular exercise, positive thinking, meditation, socializing, therapy, challenging myself in every aspect of life and yet minute improvements but then suddenly I am back to normal after 2mg of Mirt?
However I have oft been convinced that I had returned to normality before just to slip back into the LTC once again. I don't know what to take from this. Part of me wants to accept that I will be permanently this way and yet another clings onto the longing to be permanently stable again, not discounting 'normal' fluctuations in life.
Also this revelation that I can 'fix' myself with an anti-d leads me to believe my issue is purely physiological despite every Tom, Dick and Harry insisting that I should look at psychological factors first.
Is there any advice you can offer, in layman's terms this time?
