Noooo. Never trust a Prosecco wich is not a DOC or DOP, never spend less than 7/8 € a bottle.
Seen the drinking habits in North Europe you'll have to expect a guaranteed headache. Sorry.
If you can, try Cartizze instead, the king of Prosecco. Fresh and vivacious aperitif but with a 11.5 % alcohol content.
Eat something together, you won't get drunk before lunch...
