"It's been tough. Some people are saying the honeymoon is over now. If that was the honeymoon, I'd hate to be married," Nosworthy told BBC Somerset.
"It has been tough but at the same time I've learnt a lot. I'm sure the guys have also learnt a lot from going through it, compared to what we've been used to.
"Some of the worst times of adversity are when you learn the most. A lot of lessons have been taken from this season and hopefully in the off-season we can put in to place what needs to be put in place."

"The runs were there this season but they were inconsistent. It was a concern that no one stepped up to stop the domino effect of the collapses," said the South African.
"From a batting point of view, our style is very adventurous and positive, but it's a high risk.
"That's not just this season, I've looked back on these last few seasons. There's definitely a style of playing more aggressively.
