weird question, but...

Becky
Recently, I discovered I had head lice. I don't know where or how I got it, but I managed to give it to my boyfriend too. He wants to stay over at his place this weekend, where we'd sleep in the same bed, as per usual, but my question is:
is is still possible for us to treat this and not reinfect each other every time we're lying next to each other? 😰
Also, what sort of treatments worked best for any of you who have had it before? What is the fastest way to get rid of these little fuckers? I live a busy life and I can't afford to have them much longer.
