I got a prescription for SW from my GP - do I need to call before I go?

[Alambil]

I need to lose 10 stone or thereabouts... I want to get from my current size (enormous - over 20) to a 14/16 by next March, therefore I need a supportive start!

I don't know if I need to explain the script beforehand though - any ideas?

I had this, i had to ring the main sw number and they filled a form in over the phone,they then sent me info which i had to wait for as it contained a form which inhad to give to the leader of my chosen group. It took about 2wks in total (my info came the day after the group meetup so had to wait till following week). Its really simple and you can ask any questions on the phone if youre worried.
Good luck xx
