It seems like more of an anti depressant to me and not sure weather to take it?

I have had one for over 10 years but have been able to put it aside during previous pregnancy. I was doing really well recently but I am pregnant again...

My nearly 22 months old son loves breastfeeding. I do too but he wakes up quite a lot at night and with 2 other children is quite tiring. Any suggestions how...
