Oh god pistachio, how awful. I wonder if a cranial osteopath might be able to help, it might be a bit less painful than a chiropractor? Having said that I saw one for me after pops was born and he didn't help much with my pelvic/ knee pain, but I know people go to CO when PG with SPD, presume also sciatica? You might find one open on a saturday (or a chiropractor)
Thanks for the dairy free advice CSWS, esp for typing out that long list for me! I actually dont like dark Choc but have some flapjacks which are dairy free (with apples and sultanas so good for constipation) and have a few of the dairy free Choc bars for when I get a craving for Choc, also DF Choc ice cream which wasn't about last time I don't think.
Went DF on Thurs, yesterday (fri) went to watch royal wedding at a 'picnic at the pitch' at our local football stadium. I'm queuing for face painting with Pops taking spoonfuls of her strawberry cheesecake haagen daazs (sp?) to stop it melting and DH comes up and says 'is that dairy free?' 


So the dairy free is going really well! 
Joking aside, only yesterday (Fri) his skin looked a bit better (maybe coincidence) and he seemed a bit happier in himself but early days and he could have been having a good day, time will tell ... I know my skin cleared up last time I went dairy free and DH still can't drink much normal milk without feeling sick, plus my mum and her brother can't eat dairy, someone did tell me once it wasnt hereditary tho.
CSWS I noticed lactulose itself was on a list of dairy ingredients i'm using as a guide, if this is wrong pls let me know as would be better if I could stay on it for now. this is the link
Ronshar, peppa pig world sounds ace, pops would love to meet George, it's a shame it's so far for us, maybe we'll combine it with a camping trip later in the year.
