loss of appetite...

Has anyone lost their appetite with Mirena? For some reason I feel like eating just once a day. I LOVE FOOD! So this is very rare for me. It's 6:41pm now and I had breakfast around 11:30am and I don't feel hungry at all but I know I should eat. I'm not axious or stressed out, I just don't feel like eating. My boyfriend has noticed the same, when we go out to eat I'm just eating half of my meal. He stated yesterday that I usually eat a lot, so you can imagine how drastic my appetite has changed. He's worried and now I'm too. Is this normal?
