hyperhidrosis
"Suffer from excessive sweating on my face & when in hot climate it spreads to my back too.  I begged help from GP who tried me on Propanthaline which left me in agony due to difficulty passing urine & cystitis type reaction after 3 days use.  I was then passed to dermatology dept. at hospital who just said nothing could do! Oh the wonder of UK'S NHS!! Said to try propanano, which again did not work. So I did my own research and went 'cap in hand' back to my GP & BEGGED to try Oxybutynin. He said no solid evidence it works & it's just a placebo for hyperhydrosis. Anyway he gave in & said I could try 5mg a day.  I started them 5 days ago & but better so upping dose to 10mg (at night) as makes me drowsy."
