Seymore i hope its gets better for you. I feel your pain its horrible, it can only get better though. Luckily for me Heidi has only just started the screaming for no reason so i know it'll pass soon.
I've decided i'm going to invest in a walker ASAP i think thats what H may need as when shes screaming and i pick her up she tries to stand up against me and shes constantly kicking her legs.
On the plus side me and my sister held the newspaper above heidi's head this morning so she could hit if and choose a horse on the national. It came 4th 
Spotty we use the granules, i brought the nelsons ones 1st and when i went to boots to get some more they had no nelson ones but had their own brand. When i read the leaflet boots own are actually made by nelsons and were cheaper.
She seems to smile when she sees the packet. I rub the granules into her gums
