you used to be able to get them from the docs i think you still can a friend of mine took them and she did lose weight but you have to stick to a very low fat diet as the side effects kick in if you dont , any way she took them for about 3mths with no problems till we went for a night out and she wanted a keebab as you do when you have had a few and i dont think she left the bathroon for 2 days after lol she rang me and said theres oil in the loo and it wont go ive flushed and flushed and its still there i thought it was sooo funny but her family were all for leaveing home
