Sorry to hear about your panic attack. Sounds like you had a pretty severe one!
Yeah, I'd say the side-effects were pretty consistent. They didn't become really bothersome until my doc upped my dosage after it seemed the drug stopped working. That helped control my SA but I started having terrible fatigue and weight gain. And even with dosage reduction, it didn't seem to made a difference. But then I developed involuntary limb movements (myoclonic jerks), which didn't concern my doc, but frightened me enough to get off of it. Once I did, they went away. I did this without notifying my doctor at the time, as I was low on funds and couldn't afford to continue seeing her.
From what I've been told, though, side-effects from psychotropics, as well as effectiveness, can very greatly per individual. What med are you taking?
Presently, I'm not seeing anyone for my SA.
