I was on Lexapro for about 2 years. I felt ravenous for the first few months, but I think it may simply have been that I'd had no appetite before. Lexapro did make me crave sweets, though....I may be the one woman on Earth who doesn't like chocolate. No interest in ice cream, cake or cookies. I prefer sour stuff like pickles. But once I started Lexapro, I could eat a bathtub of Jelly Bellys and it still wouldn't be enough. I could also drink what felt like gallons of booze. My chemistry must have had an opening there... I eventually found that baby carrots and hummus or cherry tomatoes in kosher salt were healthier substitutes. I also mixed therapies and did a baked potato w/sour cream before bed a la "Potatoes Not Prozac." PNP suggests that sugar sensitivity and rapid serotonin depletion may correlate. Yet I only crave carbs and sugars when I'm on SSRIs! This may have something to do with the selectivity that Geebs pointed out.
I hear you on the dosage timing, too. I fiddled around with times and ended up taking it about 3 hours before I thought I was going to go to bed. This worked best for me-- even if my bedtime wasn't consistent, I usually had to get up at the same time each day, and this timing worked.
I'm just returning to meds after a year off. I couldn't even think lately-- just wanted to sleep all the time. My p-doc prescribed Cymbalta, which includes a norepinephrine reuptake inhibitor, so we'll see if I become the Jelly Belly bandit again.
Really glad to hear you're feeling better. Hope to hear from you again soon.
