I’ve taken many drugs that give me jello-brain. Any anticonvulsant makes me forget words and say ‘uhhhhhhh’ about three times a sentence. It’s very common and can partly be controlled a bit by spreading out your dose or taking it right before bed.
Trileptal gave me jello-brain. Neurontin gave me the shakes until it reached therapeudic dose and my body adjusted- then it just gave me jello-brain. Lamictal and Depakote did the same thing. Each one was bearable to a point- but needed some dose tweaking to find the best balance of effectiveness vs jello-brain.
Tranquilizers, like Thorazine, are simply doing their job so I don’t expect anything different from them.
Anti-psychotics (AP’s) can make me groggy depending on which one I take and when I take it. Geodon made me groggy so I took it right before bed and that helped. Invega gave me horrid headaches so I split the doses. Seroquel made me eat sugar till I could burst and then knocked me out so I simply stopped taking it.
