The 27-year-old defender has already played 48 times this season in which he secured his second Clydesdale Bank Premier League championship medal and a passport to the Champions League for next season again.
The Englishman and the rest of the Celtic players, though, have to play three Champions League qualifiers, the first of which comes in the middle of July. Consequently, the Hoops squad will be back for pre-season training in late June.
Ahead of the final SPL game of the season against Dundee United at Tannadice, the Parkhead defender spoke of his fatigue.
"It is a physical sport and I am starting to feel it a bit," said Wilson, who was one of the players give a recent break by boss Neil Lennon.
"It was nice to get that break and I benefited from it. I think we needed it but we probably needed more than 10 days.
"It (break before returning) is not enough but there is nothing we can do about it. The fitness people here will try to manage it as best they can but it is not enough, but you've got to do what you've got to do.
"We can't moan about it, other teams will have to come back for the qualifiers so we will just get on with it. We will deal with it, we will be fine."
Wilson joined Celtic in July, 2011 after leaving Nottingham Forest but admits he struggled in his first season in Glasgow both on and off the park. However, has settled down to life with one of the city's big two clubs.
He said: "I have got used to it and when you are doing well on the pitch you are pretty much happy off the pitch. The season has been long but enjoyable. Being successful, you enjoy it so it has been worth it."
