i'd be checking all of your radiator hoses, make sure they arent perished with holes in them. air will be getting in and will not be good... do not drive it till you have sorted the problem!

bubbles from overflow and losing coolant..... Yep you have done ur Head Gasket, had the exact same problem with mine, 2 and a half days later with a chemically cleaned head and a genuine Nissan head gasket (and a **** load of work and profanities) she now runs beautifully. If you are game enough to try yourself im sure there is a guide on here, if not better hope you have a bit of $ to fork out to get the work done. Try what Hingo said, it's always best to eliminate the smallest/easiest things before you dive in
