I live in Spain and was diagnosed with P/D about 4 years ago.
The treatment I have had has been terrific with my neurologist and nurse being available 24/7 either by mobile . or email.
I have had various medications from Sinemet to Stalevo, but am now firmly entrenched with Stalevo.
Unfortunately, I have reached my limit and within 2 or 3 days was tested for Apomorhine via an Epi pen with great success.
I don’t know how the UK works but I must say that the treatment here in Spain has been fantastic.
