"after many, many years of taking zoloft for depression, it got to a point where it was not as helpful as it once was. i visited my doctor who put me on trazodone as a booster to the zoloft that i was still taking. in 2 weeks i noticed the difference. i no longer feel depressed and feel more like my old self again. the only side effect i have had is a little blurred vision...i&#039;ll take that any day over depression."
