I was pondering on the prescription for viagra for such a while, I get mine from boots, due to the probs you initially had I chose to pay over the counter, the form you fill in has all the wrong answers greyed out so if you hit anything they want to talk to you about they will, so I kept it by the book with my answers, especially regarding my heart medication (yeah not too clever but hey), the ticket they give you is for 6 months, I didn’t give my correct contact details and it’s very easy to sign up at another boots every six months or return to the same, they don’t recognise you or ask for id
I pay about £35 for 8 tablets, though I find I only need to use half a tablet at a time giving me 16 goes for the money.
