<human>: Give me the gist of the text in a nutshell

I recently charged a trip on a credit card.  It's about $2,000 of $2,200 max.  I chose this card because it had an offer for 0% for 12 months.  I have other credit cards and have a great score, roughly 780. (according to credit karma which could be way off) I also have an overall credit limit of about $22,000 between all cards so the utilization overall is still ok. 

According to credit karma, my score took a hit about 50 points from this.   My question to you guys is,  will my score keep dropping 40-50 points due to the high utilization?  Or is the 50 points the only major hit I'm going to take and as I continue to pay it off it'll gradually go up?
<bot>: Will my credit score continue to take huge drops (40-50 pts) because of a credit card close to a max limit or is it just one major hit?
