Beginer with questions

[aprilh070203]

Hello everyone. I've made one other post concerning sweet wines. However, I was sitting around with my husband talking about what wines had been recomended this far, when I remembered that I also thoroughly enjoy a pink champagne that we actually get from Wal Mart. It might be a little on the lower class end, but I really like it. My question was, because the stuff goes straight to my head, is there a way I can save an opened bottle, and just have a glass every now and again, or will I inevitably lose the fizz. If you can offer advice on this, I'd greatly appriciate it. Thank you all.
