Sooo what now?

So In about a month I will be two years into Lexapro and it's done absolutely perfect for me. Yes I have had a few iffy side effects in the beginning and some periodically that just kick in at random but my anxiety and depression have cleared up like crazy. But that's the thing! What now? Do I begin to taper off or should I continue it since it's doing its job. I need pro answers. Btw I'm on 10mg
