Im 42 And My Doctor Put Me On 100,mg Of

Im 42 and my doctor put me on 100,mg of zoloft. For depression/anxiety/OCD order. I have taken other antidepressants that never helped this has worked wonders for me I've only been on it for about 3 weeks . I'm feeling a lot better, calmer, and can think more clearly so far My worries is I take it at night before bed but I'm still drowsy the next day. Does that go away after I get use to it? I haven't had any serious side effects other than I don't have much of an appetite. I don't want it to make me gain weight.,I've been working out a little every morning. But my min concern is the tiredness
