After 5+ years of suffering with insomnia/health anxiety at night from fear of dying in my sleep, i finally went to the doctor today and spilled my guts. I didn't even list off half of what i thought i would need to tell her to believe me. I am about to take my first dose of 50mg zoloft. Did anyone get any side effects from the very first dose? or positive results in general with using zoloft for health anxiety/insomnia/panic attacks?
