Is there anyone that is on both of these meds that can give me some insight into their experience ? I've been on buspar 15mg twice a day for a couple months and while it's helped with overall anxiety, I'm sleeping worse than ever. So my doctor prescribed me 15 mg mirtazapine and upped my buspar to 45mg per day for a week and then wants me to go up to 60. Im anxious to start the mirtazapine after reading about the potential for serotonin syndrome when these two meds are combined. I once took an ondansetron while I was on Lexapro and while I don't know if it was serotonin syndrome I had the worst reaction and basically had a 7 hour panic attack. I'm terrified to ever feel like that again so please share if you have any experience on both of these meds together
