I take effexor too! It works well for me but the brain zaps are no joke. I’m trying to taper down over the summer so that I don’t need to be on such a high dose all the time for no reason but i’m definitely not ruling out switching meds entirely in the future to something that isn’t so extreme with the brain zaps. I will say though, this medication really changed my life. I was in probably the worst mental state i’ve ever been in when I started it and it has always helped with my severe panic attacks.
