I'm on 4 medications - effexor, imipramine, lamotragine and seroquel. For ages (probably a couple of years) I've been having those "brain zaps" that are common when you stop effexor and some other meds. I hardly ever forget to take my meds, but still I have some days when loud noises or some movements give me brain zaps so intense it feels like my face is tingling and I can't hear properly. It's not painful and I'm not dramatic about it, but it does bother me.

Has anyone experienced this not in the context of withdrawal from meds? I have asked my dr but they were kind of vague and didn't give me an answer. It also seems to get worse after I work out, like when my heart beats fast.
