I do feel tired from time to time. The problems that I'm facing is more of can't wake up in the morning. At night very hard to fall asleep.
I do feel very tired in the afternoon when I'm in office. So I drink glucose to keep myself awake. Its a very tiring process though. Sometimes make feel like quitting my job and stay at home to enjoy my pregnancy.
For weekends, I like to sleep. Best of all, I can sleep the whole day!!
