Feel sick and dizzy all the time

Hey,

So i have been on Lexapro for about 6 months now, and doing incredibly well, even started today to cut down to 5mg, but over the last month or so, i have been feeling really terrible, nothing to do with my usual panic attacks or anything, but feeling really and i mean really dizzy ALL day long, and feel really nauseous after eating anything... I don't no what is going on with my body it just donesnt seem to be working very well the last few weeks, thats one of the reasons i thought of cutting back to lessen the dizziness caused by Lexapro, but i don't no why im sick all the time.. it got really bad when i came home from a holiday and as soon as i stepped off the play i felt sick, and been sick every time i eat since then,

Anyone else get this? its really starting to worry me, and im am afraid if i worry all the time again i will get panicky, which after working so hard is the last thing i want in my life again as you can imagine..  Hope someone can help..
