Prohealth will deliver Guaifenesin or any other product to Holland. I am in England & have regular deliveries; they are very good. To do the Guaifenesin protocol you also need a copy of Dr St Amand's book 'What your doctor may not tell you about fibromyalgia'. This is available from Amazon, from the UK Guai Support group on Yahoo, & probably lots of other places. I'm doing the protocol,like all the UK group,without a supervising doctor because there are none here.
