About four years ago I decided to go cold turkey from Zoloft and Depakote. After a month I went bat shit crazy and got back on them. Since then, when I wake up from a deep sleep and often at other times as well, I get this "pfft, pfft" sound inside the left side of my head. The doctor says it is blood pressure balancing out. I'm not sure I buy that. Online searches turn up nothing. Does anyone know what this might be? Edit: I also have Tinnitus.
