If I just woke up this morn feeling like I've caught my fams resp. Inf. Should I go to dr. Now/wait?

Wait. This is the beginning of cold season, and kids in school play a vector's role in transmitting these viruses to others, particularly parents. Keep well hydrated, rest (ha!) as much as you can, use Acetaminophen or Ibuprofen for aches, pain, or high fever. Usually these colds last 5-7 days. Improving each day. If you're still sick , or develop new symptoms, or get dramatically worse, see doctor.
