I have been on Zoloft for years, but recently they changed the drug manufacturer. To add into the mix, I eat at least one pound of turkey every day (bodybuilder). Recently I've been experiencing difficulties concentrating, cloudy thinking, sweating, and shaking. Could this be a possible serotonin syndrome? Has anyone experienced this? Not sure if it's just stress (finals next week), new drug manufacturer, or the turkey. Any thoughts?
