i'm on day 9 of lexapro 5mg. i take my dose at 6 pm. i always get super anxious &amp; feel like i'm going crazy with racing thoughts 30 mins before my daily dose. the brain fog gets more intense too. is this my body adjusting to it? if so, will it ever go away? i always dread this feeling. sometimes it calms down once i take my dose or gets worse. i just don't want to have to take a klonopin 0.5mg everyday to calm down.
