hovering close to my credit limit

the rate at which i am chalking up the bills, i'll be broke before i even know it...

things bought over the last 2 weeks...

(i) return air ticket back to singapore ... xxxx amount (the amount is enough to pay for 5 months of rental in denmark)
(ii) return air ticket from copenhagen to krakow/warsaw (poland)... 250 dollars
(iii) return air ticket from aalborg to copenhagen for the trip back home... 180 dollars

ok, here's the crappy part... joy at seeing everyone back home and the opportunity to visit poland... priceless... but to be on the safe side, think i will either (i)send my credit card into cold storage or (ii) cut it up before the spending bankrupts me...
