OZZY OSBOURNE - OZZY'S PAINFUL VIAGRA EXPERIENCES

Rocker OZZY OSBOURNE insists wonder drug VIAGRA has done very little to enhance his sex life - because it always leaves him battling excruciating headaches.

The former BLACK SABBATH frontman has consumed the anti-impotence pills on many occasions when preparing for sex sessions with wife SHARON - but he's often been left in agony as a result.

Sharon says, "In our bedroom we never get to the love-making because Ozzy's like, 'Oh, my head!' We never get past the headache!"
