"i have depression since 2007 and already have three relapses till now. for my first treatment, i was given lexapro and as most anti-depressants it took around 3-4 weeks for this drug to fully take effect. side effect to me was minor eg. dizziness, loss of appetite. with a combination of exercise. i did recover although not fully, after 1 year. on my 2nd relapses (failed biz investment), i was again given lexapro, nothing new to me and the drug itself took effect fast and i felt better after around 3 weeks and move on to a new job. recently due some persistent health problems (stomach ache), my depression again came back. i saw my doctor and again given lexapro. the effect was good and felt better within 2 weeks and now i try to exercise 4 times a week."
