help relaxing ?

[TractorBoy147]

ive played for 5 years now highest break in match is 84 i get to 50-70 fine but recently stopped smoking and find concentrating that little bit more difficult, the 50-70 breaks are not as often as they once were this is most frustrating for someone working towards their first match century. apart from drinking as i drive mostly any suggestions on what needs to be done to get the confidence and concentration back?

Not assuming your unfit or anything but keeping fit and active is suppose to help a lot with concentration levels
