Latest: I got a prescription for another month of tablets. Our_Lass didn't and is suffering again now.
I'm supposed to stop taking the tabs 7 days before seeing the doctor on the 14th Feb.
Good old Tesco. They sell a 12 pack of Ranitidine for £1
Bit of googling, and commom sense, says 1 or 2 of these a day SHOULD have a similiar effect.
Our_Lass is going to guinea pig this for the next week. If she's Ok, I'll trial run them and sod the doctor.
