Aveeno lotion symptoms and conditions

I have been on Zyrtec for three years (Every day) haven't noticed mood swings in myself? My mother also takes them every other day and is not particularly moody. Although she has trouble sleeping which she attributes to the menopause But if i don't take one within 24hrs I get very itchy and hive up..now that I'm breastfeeding I've just noticed my daughter is very irritable..and am beginning to think it's related to the zyrtec. I'm changing to claratyne in the morning to see if there's a change..very,very interesting and scary reading all the side-effects!!
