Anxiety/Severe Panic Attacks Lexapro

Has anybody taken Lexapro for anxiety and depression i was on prozac a few years ago(had bad sideffects and horrible anxiety) then got switched to zoloft (gave me bad anxiety and depression)then paxil which worked but recently stopped working now I got prescribed Lexapro 10mg and i am scared of the side effects has anybody taken it before did you experience any sideffects ? I've read that some people get increased anxiety at first and bad nausea (i have a fear of throwing up) i took my first dosage today but i am scared as to how my body would react
