Although I haven't had to have it done I know quite a few people who have and the most amazingly universal phenomenon is the improvement in each person's face color. Gone is the pallor, the gray undertone. And they invariably say that they feel a great deal better than they used to.

'It only hurts for a little while
That's what they tell me, that's what they say
It only hurts for a little while
And all your heartache will pass away"

*G*

So go for it. Good luck.
