I'd make smaller changes in your ratio, change 2T in the front or 1T at the back and get used to it.

So 44x16 would probably be my vote or conversly dropping to 42x15.

Note that:
Cogs are cheaper than chains and easier to change. But higher teeth counts last a little longer as the wear is a little less, also have more engagement so its much harder to drop a chain etc.

Chainrings are not always available in certain teeth counts depending on your bcd/pcd.

You may have to adjust you chain length (if you drop a cog size) or increase it (ie get a new chain) if you go for a bigger chainring.
