Does this seem right?

I started on 25 mg and worked my way up to 50 mg, per my doctor. It was working super well for a few weeks - I felt calm, no racing thoughts, I was sleeping really well for once. It was so nice to feel improvement. Then it just wore off. My racing thoughts are back, I feel stressed, and sleep is bad.

Does this seem like I responded well to the increase and should discuss another with my doctor until we get to a therapeutic dose? Anyone else experience this?
