Hi! Well, unfortunatly most meds for moods have to be taken all the time. I would try lexapro... I have a few friends that take it and I used to take it too. It's mild and should help. It's worth asking your doctor either way. Good luck!
I believe the one i was on that helped the best was sarafem (i'm 90% sure that was the name) it was for depression and helped to balance hormones too. I'll double check the name and let you know.
it is sarafem i was on. It used to treat PMDD. so it might be something worth trying. Best of luck to you.
