Cfs specialist

Please can the advsors reply to this. Or gorden any one would be fine with some knowledge about it. Im wanting to ask about refusing a medication presecribed by the G.P. i have good reason to not take it. Im going to a alternative herbalised practioner. I been given good advice on healing my condition with herbs. I havevseen it improve.So i decided not take medication as it interferes with it working. Now i asked to be referred back to cfs specialist for support with my other medical condition. They are asking for results first tests. It shows i do not take prescribed medication. But the G.P is trying pressure me into taking it. Im pretty sure cfs specialist are going to refuse seeing me also because of this. I read up that i have rights under the patient rights on the NICE nhs page. That if i need a service to help me they cant refuse to see me if i reject the medication. I have right to reject medication if not suutable for me and still be seen supported by nhs services as i want medical letters of support from them to for my medical coming ESA. Please can you give your opinion on this knowledge. As i am very confused when i should feel get more support. This service supports me in my rehabilitation. Can i complain if they refuse me again. How fo i do this ask G.P to rewrite a letter to them. Or fo i contact NICE. To complain thanks nicky.
