Quick update:
2 months and a week since last injection (1 injection of 100mg): Libido has returned. Sleep schedule is better (now I awake at 5am instead of 3am on somedays). Brain fog has lifted slightly and there are windows and waves. There are still waves of anhedonia but the effect is minimal compared to when it was at its peak (I'd say roughly 10-25%). Akathisia is almost non-existent and only appears in the form of teeth-clenching once in a while, again, very minimal effect. I still experience a lot of drowsiness, especially in the early morning and waves of racing thoughts/anxiety; however, these are manageable.
In my case, these improvements are gradual and rather subtle, they don't happen overnight. In my experience, the effects of invega acts in a decreasing and cyclical manner, such as the example of dropping a bouncy ball on the floor: the ball will bounce many times off the floor, the next bounce's apex will be lower than the previous bounce, and so on until it ultimately stops bouncing (hopefully this is the case).
I find that dopamine-boosting activities are very helpful in managing these side effects and also are a great way of passing time. Some examples are: exercising (walking, swimming, cardio), journaling/writing, watching tiktok/content on social media (when other activities are too hard to perform), getting sunlight, traveling, etc
Overall, I think eating well, sleeping well, getting outside more often (for sunlight exposure among other things) helps in recovery.
