Urgent need help!

<p>okay so I didn't know where to put this. I am editing my college essay for the LAST time before turning it in and I need to know which sentence sounds better and is gramatically correct:</p>

<p>I couldn't resist trying one
OR
I couldn't resist to try one. </p>

<p>THANKS A TON</p>

<p>First of all…</p>

<p>Do not use contractions in essays! :)</p>

<p>So…the best way to word that sentence is…</p>

<p>I could not resist trying one.</p>
