You should also request your consultant to write to your GP Laura.
Mind you my step-daughter has a problem at the mo - eats like a hoss, 5ft 8 and is currently 6 stone 2. So GP sent her to the dietitian at the hosp who said she should be prescribed 2 of those Nutrisip things a day, which should help. Doctors said they were too expensive and would only let her have 1 a day. She went back for next hosp appt this week and dietitian went mad. So somebody is gonna get a really stroppy letter middle of next week .....
Trouble is she had a baby last year and had to come off all her psych drugs instantly and she isn't allowed to go back on them without seeing the psych and they wouldn't refer her back for months and months. Too weak to pick her baby up now. She's virtually transparent.
