Hiv infection through blood transfusions is very rare in the us because all donated blood is carefully screened.

HIV can be passed on when a person recieves HIV positive blood products, like tissue or organs. However, all such products are screened before they are used to avoid this happening. Additionally, it is not possible to get HIV when giving blood, because clean, sterilised needles are used. So the answer is true.

Probably because you wake up early. even when i get a good nights sleep i still feel tired if i wake up early. or maybe you just need coffee.
