I'm only 3 weeks off right now and got goosebumps again playing guitar. I really felt the music. The past few days I've been feeling really well not as self absorbed and conversating more and have an overall more positive outlook.
To the people that say this drug blocks your dopamine receptors permanently, it is true they do. But the good news is, is that receptors don't last forever, they regenerate which means recovery is absolutely possible. Though this could take time. In fact your body upregulates dopamine receptors (creates more) due to them being blocked. This could be perhaps why some people can go back into a psychosis when off very fast.
For erectile dysfunction try Blue Rhino 10k at the gas station or order it. It works 200%. Had a gf she was cool with it. Takes about 30 mins to work and lasts for a couple days. (won't make you constantly erect just makes it work like normal but its rock hard when you stimulate it and it will last as long as you need it to) Id see her on the weekends and take it on the way to see her.
Just sucks because you have to pay to have sex now.
There is also hope if full recovery seems not to come. There is a drug called i've been looking into called Welbutrin that treats depression. It isn't an SSRI and doesn't have all the long lasting terrible side effects. Does have side effects starting out though that fades. Gives you energy, motivation, happiness, and increases your sex drive. It is a dopamine and norepinephrine reuptake inhibitor. That's how you get the dopamine folks. It's even been used with AP. Look online for the studies.
For the drop in IQ and mental function nootropics and other neurogenesis inducing supplements are what I'm currently researching.
Another tip, if you plan to quit, after your last injection, tell your doctor you want to switch to pill form so you have them if you need them in case you relapse. (hopefully not)
That's all I have for now but hopefully I've provide hope for Anhedonia and Sexual Dysfunction and whatever else.
