Hormone Problem?

Lately I've been tired and sleepy. I think my body tries to tell me to get more sleep and rest because blogging made me sleep very late at night. My appetite also changes lately. Now that I'm used to drinking tap water and bottled water, my taste buds are very sensitive to sweet and salty. I noticed yesterday that my hot choco drink becomes sweet already after I pour 2 tbsp of sugar while cooking it. In the past, I put a lot of sugar because the hot choco still taste a little bitter but not yesterday. I even bought a carrot cake that I really love to eat after dinner as my dessert but I only had a bite of it and didn't eat it for 2 days now. In the past, I took 3/4 inch slice of the cake and finish if right away. But the other day, a bite is enough for me. I also tried to avoid salty foods lately. Hmm Even the junk foods that I like to eat before are now sitting around coz I don't like eating them anymore. It's good that I'm not eating sweets, junk foods and salty foods lately. This is good for me and my health. Not sure though if my hormone is making me do this but I'm thankful that the change is for the better. :)
