It kind of just depends for me. Mine tends to be worse an hour or two after I wake up and in the afternoon/early evening, but it's been all over the place in the past week. Recently I had an anxiety attack at night while as I was falling asleep (very rare for me!) and this morning within a few minutes of waking up I had an episode. The unpredictability makes it fun...NOT! It does keep me on my toes I guess..
