I am over 60 and have tried Cialis with doctors prescription and it didnt seem to work to well,Am now on Viagra 100 it seems to be trying to work but its not 100% the problem is that both of these give me a really bad headache just behind my left eye,some times lasting for 24hrs,My Doctor does not seem unduly worried by this but its a bit of a put off.Any input into this would be appreciated,
Thanks
