I have been on Zoloft for 2 weeks now. 1st week at 25 mg. second week at 50 mg. I feel no effects except feeling sleepy. I take the med when I wake at 6AM. I have heard that if Zoloft makes you sleepy that means it will not work for you, is this true? Also I am wondering about weight loss, I heard that Zoloft can have the positive side effect of weight loss, and I have not had any nor do I see how I would when it makes me so drowsy, does a person have to be on the Zoloft for a longer period of time or at a higher dose to get that weight loss benefit?
