Hi Chas B and my best friend Lynne, I have been taking 50 mg a day Sildenafil since Oct. last year sometimes it does give me a headache and a stuffy nose, but, after all this time, things have got better and I actually achieve 80% erections, last Oct to improve things my ED nurse gave me some 100mgs to try and gain the missing 20%. My friend Lynn thought the world had gone mad, and they were trying to kill me off, but no, it worked, and I'm still here, lately I break the 50mg in half and take half in the morning with my porridge,lol, I'm sounding like a right oldie, and the other half after dinner at about 7pm and I think that keeps things ticking over with the occasional stirrings, then, on special occasions go for the big one, the 100 miller. Lynne you would be proud, but don't mention this to John,I don't want him getting upset. I do go along with Lynne when she,says in her and johns case it took about 2yrs so I'm hoping by Sept next year things may be back to normal, I may for once take Lynne's advice and ask the lovely Wendy, my ED nurse for Levitra, that did it for her john, but in the meantime plod on more in hope than anger. My very best wishes and a happy new year to you all. Diesel xx
