"week1 dizziness, nausea, no appetite, foggy feeling, stomach growling. week 2  same as before plus sweating, bad gerd,and insomnia. almost stopped but decided to stick it out. week 3 everything slowly disappeared. now on week 4, much calmer, lost weight about 8 lbs, blood pressure dropped to normal readings, i have more energy now i am walking everyday, still feel like myself, not numb like some reported . reason started was i had 2 deaths in a month and was losing it. in the past i have tried prozac, lexapro,  effexor, zoloft and many others nothing has worked as well as celexa. my advice give it time, be patient . like many things it&#039;s worth waiting for. good luck to all!!"
