it made me an insomniac...and if i did sleep i'd have the most vivid horrible nightmares....so i guess u can say it didnt make me sleepy...BUT my dr said that those side effects are RARE...so if you havn't experienced them don't fret. I think with most drugs you will get less tired in time...apart from sedating ones lol...so maybe you just need to get used to the drug..that is what drs have told me anyway...I guess if it does make you exceptionally drowsy and sleepy you could ask your dr if you could change to a medication....that keeps you alert rather than sleepy...since you work with children.....
