thanks for using health care magic.
There are two notions that you need to understand. The notion of HIV
infection and that of AIDS
. HIV infection simply implies that you have been infected with the virus which after a period of time say five to ten years will progress to AIDS which is the disease.
Tests that are used to determine if there have been an HIV infection are only sensitive after their window period ( period between being infected and when test can be sensitive). During the window period, a negative test could be a false negative in which case the test was not sensitive at that point. Rapid diagnostic tests become sensitive 3 to 6 months after becoming infected and its for that reason that you were asked by your doctor to re-take the test in three months time.
AIDS as a disease destroys the immune system there by giving room for opportunistic infections which could be any where and present with diverse symptoms.
However, saliva has not been shown to be infectious unless the bits of blood are mixed with the saliva and when it gets into the penile orifice or into wounds.
Concerning the sleeping issue, its probably a simple behavioural thing or due to stress
Best regards and hope this helps you.
