I've been on zoloft for about 6-7 weeks now and i was doing well on it but there was one problem. I was in a very bad sleep cycle where i would sleep from 6am to 3pm. I decided to try fix this like a week and a half ago and i gradually started fixing it by staying up later each time. So for example i would stay up until 8am one day then 11am the next and so on until i done a full circle. During that time i had to take my medication at different times. I full fixed it like two days ago and since then i've been feeling really crappy. My symptoms are coming back and i'm also feeling like i have a cold too. Why are things getting worse for me again, could it be that i was taking my meds at a different time for about a week or could it be the sleep deprivation catching up on me?
