I'm 36 weeks now. Is it normal to feel extremely tired to the extend that you'll rather choose to sleep than to do anything else? At the same time, appetite reduces too.

Yes. This is pretty common. As the baby gets bigger, you will definitely be more tired than ever. I do this all the time when I'm was preggy but every pregnancy is different. Jia you! Just a qhile more to go ... will be seeing yr baby soon.
