I've been taking 50 mg Zoloft for 4 days and have noticed some things. Loss of appetite, increased anxiety, periods of agitation, sleepy but keyed up and possibly periods of increased depression. Is this normal when you first start the medicine and do the side effects get better? Also taking a sleep aid at night. Been depressed for about 2 mths now along with the anziety. This is my 2nd attempt to find the right AD. Thanks
