Centre Morgan swapped Newport for Llanelli this summer and admits the change was needed.
He is only 25, but has struggled with injuries since bursting on to the scene at 18 and starting Wales’ 2015 World Cup quarter-final defeat by South Africa.
“It was properly a fresh start. In myself I needed something fresh, just mentally a new challenge. I think my performances started to drop with the Dragons,” Morgan said.
“I was hoping coming here would give me a fresh start and I think it has. It has given me a different outlook to rugby.
“There is such a different way of playing and the training and environment makes you enjoy coming to work again.
“Obviously, it is well documented I have had a few injuries, but hopefully they are in the past now.
“The programme is good here at looking at my previous injuries and the Scarlets are a professional team taking care of me. All has been going well so far.”
Morgan’s injury struggles weren’t helped by a diagnosis with Type 1 diabetes, but he is taking inspiration from England and Exeter’s Henry Slade who has the same condition.
Morgan made his first Guinness PRO14 start for the Scarlets against Benetton.
He said: “If I had given up I would have always looked back with regret. There are other boys playing with diabetes, Henry Slade at Exeter is a shining example so I know it is possible.
“Even if I was the only one I would still have carried on. It was a bit of a whirlwind in 2015 and I wish I’d taken it in more than I did. I was only 18 or 19 at the time.
“A couple of years after that I got a few injuries and it did get dark at times, but there is no point looking back with regret.
“I’ve been limited in what I can do for the last few years physically because of injuries, but we’ve got a good programme here and physically I feel as good as I have done for a long, long time.
“I’m looking forward to showing the physicality I have done in the past.”
