Liquid b-12

Hello everyone, quick quesiton. After surgery are you supposed to take the 1 oz of liquid b-12 once a week or once a day? I got the kind Mercy Capital recommends but the box says to take it daily. I have not had my surgery yet, just getting everything ahead of time so that I am ready. I found a great deal if anyone is interested. I found it on ebay and got a case for $25.00. Yes 20 boxes with 2 bottles in each box. I think I have enought to last a lifetime. Although it expires in 2008.

You're supposed to take it once per week, but I take mine at least two or three times per week. jean
