I have to say, dried apricots work for me. I once munched on rather too many in my first pregnancy and OMG! I had major squirts! Sorry, but it might help.
I have had angry moments too, mostly because my 7 year old has been driving me up the wall, but my husband has packed me off two weekends in a row to my mum's to chill out and I have to say, it's really helped and am much calmer. I think tho, it was definitely when the placenta was taking over and my hormones were all over the place, I was also completely exhausted and had no patience. Better now tho. still, not before a truck driver got it in the neck for blocking my way to catch a train with one minute to spare as he was looking for a building. I was going NUTS, leaning out the window - "I HAVE A TRAIN TO CATCH!!!" His response; "Eh, cin ye tell me where Agilent is??' Aaaaarrrrggghhh.
Needless to say, I missed the feckiin' train.
