I've been on it for quite a long time in the past as an add-on therapy with various antidepressants.
Not a good experience. It gave me strong akathisia and I had to take Akineton (Biperiden) for how bad it was. Problem is, Akineton is an antimuscarinic, not the best thing in the world if you have to study/concentrate. Oh, and it didn't do anything depression-wise.
Altough I have to say that between the atypical antipsychotics I have tried (always to boost useless antidepressants), it's probably the most tolerable.
Compared to Paliperidone, Olanzapine and high-dose Quietiapine it's gold. All of them make me extremely dysphoric, zombified, suicidal and lethargic with only one dose. All of them give me akathisia too, wich combined with sedation feels much worse. I took only one or two doses of all of those and had to quit immediately.
The different effects are probabily due to the fact that Aripiprazole (Abilify) is atypical even for an atypical AP, as in lacks significant antagonism at H1 at alpha-adrenergic receptors, and, most importantly, is a partial agonist at D2R and not an antagonist or inverse agonist.
Personally I wouldn't touch that shit again even with a 10ft pole, but I'm not trying to scare you.
Maybe you'll have a positive experience, everyone's different.
I don't like the idea of long term treatment with AP, the side effects like the risk of tardive diskynesia (wich can be permanent) outweight the benefits IMO.
Also brain damage is to be taken into account. High-dose Haloperidol and Olanzapine decrease monkey brain volume from 8 to 11% after 24 months. That probably applies to all strong D2R antagonists/inverse agonist, as I said Abilify could be different. Not a thing for me anyway.
