What are HJ's and Maccas ? I just moved to Australia.

I have thought about the cheeseburger but when ever I'm in a car I get nauseated so I dont' feel like eatting. I will have to get my dh to go out and buy some.

Last night I had mashed potatoes with sour cream. Another time I had sweet potato (yams) mashed. Good cause they don't have a strong smell.

Anyone taking any prescription medication ?
