female age 40 started zoloft 9mths ago ,after I found out my husband was having an affair for a year and he left me and our 3 kids for her and her 2 kids.I was so depressed and physically sick.I started at 50 mg and after 6 months the doc upped the dose to 100 mg.It does help me on the every day stress of going through a divorce and im not as depressed,but I find every thing is such a chore,my energy level is zapped and that some times can get me down.My favorite time of day is bed time ,because all I want to do is sleep!!!! I am wondering if I should ask my doc about switching to some thing else.
