My husband has been in bed for nearly three days with it. Every time he gets up, he throws up. He's rung the GP who prescribed some anti emetics, but he still says it's too bad to get up. He doesn't want to eat. I guess I'm wondering if anyone has any experience and knows how long this can go on for, or what I can do to help. I'm trying not to worry about the blurred vision he gets periodically, the Internet seems a bit funny on that one!
