Any tips on playing sixteenth note triplets with sixteenth notes?

[lilyshan]

So I am trying to learn Beethoven's Piano Sonata No.1, Op.2 No.1 second movement (Adagio). I was able to learn two pages of it. The third page I had trouble playing the sixteenth-note triplets with the original theme. It just doesn't come naturally for me.
