I agree with the sentiments of other posters regarding stress.

I completely avoided other people as much as possible - including my wife and children for a couple of months and before I knew it I was back working again.

It cost a fair bit of money because the kids went to a childminder after school, but it was money well spent.

It also took a lot of patience and effort from my wife also as she took the children out all weekend or looked after them whilst I was in another room.

Avoiding noise and stress is crucial, for me this meant isolating myself and getting quiet rest. The other crucial component was an antidepressant which took my stress levels down further.

Reflexology and massage also helped.

Good luck with reducing stress because this helps recovery.
