BTW.. many people complain about Aripiprazole causing severe anxiety.. it also does that to me.. why is that? (If I wasn't on Clonazepam I already threw in the towel)
That, could, I'm afraid, also be a result of the partial agonistic properties of this drug.
It's got partial agonism of multiple serotonin-receptors, and it's also a weak SRI - increased serotonergic activity have been connected to anxiety in some patients - hence why there's a growing hypothesizing that the reason some SRI's work for anxiety, only when they reach a much higher dosage then for depression, is through down-regulation of serotonergic activity (as a response to the tremendous overload the SRI causes).
There's also the potential partial Norepinephrinergic agonism effects - many people feel such effects cause anxious behaviour in them. (which is logical... if you consider what NE actually does... it's a stress-hormone after all.)
Brexpiprazole is supposedly the more sedating, calming of the two - it was specifically created to be less stimulating - might also mean it's less anxiogenic.
A quick glance at the pharmacology of Brex', reveals that unlike with Aripiprazole, it's effects on Alpha and beta receptors is NOT undecided / no data - but rather, square across the board, on the ANTAGONISTIC side of the fence. Yes, some of those receptors are auto-receptors, BUT... since it antagonises almost every type, it won't matter, NE-signalling will still be lowered.
So yeah... partial agonism of 5ht, Alpha and Beta -receptors could be giving you anxiety.
The restless feelings are actually consistent with other drugs which cause a sum-total increase of NE-activity - MIRTAZAPINE also causes something similar to akathisia, a kind of restlessness, and, in some, a slight bit of anxiety. Generally speaking though, Mirtazapine is so friggin' sedating that it smothers the stimulation enough to be more anxiolytic all in all.
