But it just feels so iffy because I would be 'giving into temptation' as it were.

... even though I know that I could control it and it wouldn't ruin my life.

I try to excuse myself by saying, "Well, you'll never know unless you try it, so you'd be in no position to judge!"

But is that a valid excuse? It sounds like one to me, I just want to make sure I'm not decieving myself.
