Hello! I have been taking Viibryd for about 7 years now. I also suffered from brain zaps (i call them brain shivers). I found that taking the viibryd at the same time every day is key. If I wait more than 23 hours before I take it, I get my brain shivers. But if i take it at the same time (or earlier) each day, i dont get them! Also, you should be eating with Viibryd as it dissolves easier and you get the full dose. I know EXACTLY what you are going through and i hope you get better! Prestique was way worse for brain shivers than viibryd so I’d avoid that if they recommend it.
