I started on 20mg taking a pill daily in the morning, I had little to no side effects and for the first couple months was "ok" had a pretty harsh panic attack so after seeing my doctor for a follow up a few days ago she upped my dosage to 40mg daily and since then Ive had horrible headaches and kind of shaky hands. I don't know if anybody else has experienced these side effects. I messaged my doctor so see what she wants to do. But its been miserable.
