Air conditioner really kills mileage

I had the air conditioning fixed in the slug yesterday. About time, temp was in the mid 90's and the humidity was in the low 80% range. Up until I had the ac fixed I was running 90 mpg for 370 miles. I had to do about 80 miles for work and ran the air, by the time I got home it was 82.4 mpg for 450 miles. I knew that ac hurt mileage but the ac combined with my little engine made my poor car even worse as far as pulling power goes, I was driving with little to no wind and would compare it to driving into a 20mpg headwind.
