Yes, we're lucky to have 'the Doc' to offer his Opinion - so no pressure, then, Doc!
- on matters like this.
I know that when, after about 10 or 11 years of 4 x Sildenafile a month, they weren't proving as regularly effective as they had been when my GP first told me that my disability qualified me for a NHS prescription of 4 a month, I went back to the surgery where a Trainee GP on placement checked the Formulary and found that 4 x Tadalafil might be more effective for me.
They have been; and for one who's no longer in the first flush of youth, I can report that, when I wake up on the morning
after I took a tablet - and benefitted from it the previous day - I do so with a 'semi' on.
I haven't punted on consecutive days since the extremely early days of this pastime 15 or so years ago and I've ni plans to do so at the moment. But it's reassuring to know that, if I did, the SP and I wouldn't have to work too hard to get me sufficiently hard, if you'll excuse me playing with words!
