i have the worst periods. i am not depressed during the rest of the month, but on my period, i get soooo depressed. i cry for hours and my eyes sting for days afterward. last time i had my period i took 1mg of ativan and it really helped. i was shocked because ive tried everything else. i dont want to take anti depressants because i am not depressed the other 25 days a month. is ativan ok once or twice a month?
