Is it possible that an antidepressant can completely eliminate your social anxiety or do they only take the edge off?

I just want to know if I’m putting too much hope into zoloft completely getting rid of my social anxiety. It’s like I’m waiting around for my social anxiety to be gone. I will sometimes go grocery shopping and the anxiety is still there. Not as strong. But I’ve been on zoloft for 5 weeks now. the first week 25 mg and then i went to 50 mg for a week and now I’m at 75 mg. Is this all the relief I’m gonna get.

Also if I drink while on zoloft, will it ruin the effectiveness?
