Courtenay Conundrum

Can you work out what are the next two numbers in the following sequence:  3, 3, 5, 4, 4, 3, 5 ?

And just as a random thought, not that it applies to many of us, but why is the word “abstemious” a little bit unusual?  To answer, phone Paddy on 841253 to not get a prize……

Answer to February’s puzzle is 90 stamps – well done young Tom and everyone who worked it out correctly.
(I bought 10 x 10p stamps, 20 x 2p stamps and 60 x 1p stamps)
