anyone know a way to reduce or stop snoring?

I'm 29 weeks and for maybe the last month or two my husband has been saying I'm snoring. It's usually only when I'm laying on my back so he just pokes me and I roll over, but lately it's been when I'm on my sides aswell. He says he doesn't mind, but I know when he snores on the odd occasion it drives me up the wall and I feel bad that I'm waking him up several times a night when he has to be up so early for work. So I was wondering if anybody has been able to reduce or stop themselves from snoring during pregnancy? I know he and I will both be woken several times a night once baby is here anyway, but for now I'd like for him to be able to get as much sleep as he can lol.
