Mel Gibson has splashed out $100,000 on a machine to help him cope with his stressful private life.

The 'Braveheart' actor, whose wife Robyn filed for divorce in April, is struggling to cope with the attention surrounding the breakdown of his marriage and has invested in a device to increase positive energy in his body.

A source told National Enquirer magazine: "Most people would look at the flow machine and think Mel has lost his mind. You lie on this machine and strap your feet in. The device then emits some kind of torsion field waves that are supposed to unlock clogged energy which eases psychological tension. It is pretty weird, but Mel swears by it."

Mel - whose new girlfriend Oksana Grigorieva is believed to be pregnant with the couple's first child - has reportedly experimented with several different stress-relieving treatments but is now convinced he has finally found a therapy to help him remain calm.

The source added: "From telephone healing sessions to therapeutic foot baths, Mel has tried it all. The flow machine is Mel's latest holistic gadget.

"Some in his camp are shaking their heads and saying Mel is getting weirder with age. They think the flow machine is just another part of his midlife crisis."
