Hi there. Just a little background. I was on Pristiq 100mg for MDD for about a year. I've made some great progress and was having sexual difficulty at this dose. My doctor lowered my dose to 50mg. Ever since then I've been in and out of "funks." My mood has been up and down. Sometimes I feel good, other days/hours I feel overwhelmed with my old levels of depression. Should I give it some more times for the chemicals in my brain to balance it out? Or do you think it's about time to schedule a follow up appointment to re-up the dose to 100? I understand the brain takes time to re-calibrate serotonin levels, so I hope this is the case here.
