Hi there just wondering how long the side effects of Zoloft “ insomnia “ and “sleepless “ nights last , recently diagnosed for PTSD am hesitant on starting this med I was previous on mirtazapine to help sleep as I am suffering badly at present Insomnia almost nightly . The Dr are aware this and prescribed this I am just confused I guess . Looking to see any one else’s experience with the sleep problems side to it
