I started back on Sertraline 50mg on the 13th of this month, so just under 2 and half weeks ago - as I couldn't be dealing with the 10mg Citalopram causing sleep disruption (and indigestion!)
Strangely, even though I had been on Sertraline for 4 years prior to last October, when I restarted it up again, it's caused...Sleep disruption! Never had that one before with Sertraline! Also mega-headaches from time to time, again, not had those ones before!
The sleep thing, I hope will get better, it tends to be waking up about 4am, and overthinking things, so difficult to get back to sleep again, hoping this will calm down as I settle back into the meds.
