What the goddam are these head zap things about ? I'm at the start/middle/end/start/middle point of Effexor withdrawal, and every time I move my head suddenly or move my eyes around, I get this buzzing sensation in, er, well, kind of 'behind' my eyes and I feel like I'm going to fall over, even when lying down - if that's possible. I'm also getting strange sensations on the soles of my feet...kind of a numb/cold feeling.
I've noticed that quite a lot of people have mentioned these head zaps during withdrawal...does it last ? It not particually disabling, just bloody annoying. I'd be curious to know the biological basis for this so that, of course, I can obsessively worry about it.
