Condition for the past 4 months

My condition for the past 3-4 months has been like a roller coaster.

1. Can't even sit in front of the PC to blog. (1st 3 months)
2. Experience diffculty to burp - and it is making me feeling nauseous !
3. Drinking water is almost impossible ! Needs some honey or ribena in water, else water taste so bitter that I felt like vomiting. 
4. Can't stand fishy smell, hawker fumes, food in mouth- the aftertaste (esp eating hawker food), butter smell, seafood, durian smell (but i used to love it!)
5. Crave for minced meat. veggies ok, but depends on the mood. (used to like veggies) occasional cravings for fast-food.
6. Some occasional brown discharge on my panty liner.
7. Low immune system (having sore throat earlier in May)  
8. Always want to sit or lie down like an old woman
9. Always want to sleep like a pig (even though mind not sleepy, but the body seems to like the bed)
10. Always wake up early in the morning/wee hours feeling hungry (when i am actually not a morning person !!!)
