Take from the following what you want.......
I've never taken lexapro...but I've taken similar drugs in the same class (SSRIs), Paxil, Celexa and Prozac. I've also taken Wellbutrin and effexor. IMO....wellbutrin and effexor are much better drugs for someone concerned with physical fitness and appearance.
The drug companies won't say this but the SSRIs have tons, litereally tons of bad side effects which can really vary depending on the individual.
Currently I'm on no medications.
But while on I was on Paxil (an SSRI like lexapro) I had terrible carb/sugar cravings, if I had one piece of candy I had to have twenty and I couldn't stop. I also craved alcohol, basically because it converts to sugar in the body (my doctor told me that at least). The alcohol cravings were the worst probably because I was attempting to not drink at the time.....I gained about 50 pounds while on SSRIs. I also had a bitch of a time trying to sleep. And I suffered from terrible night eating, I would get up in the middle of the night and eat huge amounts of ice cream, candy and/or anything sugary or high in carbs. In addtion to the above I had extremely low motivation which led to me not working out as well.........all in all, the SSRIs worked very effectively in causing me to gain massive amounts of weight. I didn't care about myself and basically felt like shit. I wasn't depressed, but I wasn't much better off.
So thats my side of the story.....btw, I've experienced none of the above behaviors since quitting SSRIs. For about 3 months I took wellbutrin...it was very good for my depression, gave me positive energy and made me feel motivated. It also gave me none of the negative sides of the SSRIs............sooooooo, in short, if you're experiencing any negative effects from lexapro, see if your doctor can ween you off of it and onto either wellbutrin and effexor. Forgot to mention, I also took effexor for a while, it was great as well, my motivation to workout was unbelievable, I was almost insane in my dedication. I guess it has something to do with the dopamine stimulation, I think thats the brain chemical which influences motivation....both wellbutrin and effexor work on this brain chemical
