For the last 20 + days i have been having trouble sleeping. I can only sleep for max 6 to 7 hours. After waking up i try to go back to sleep but As soon as i fall asleep i have  breathing trouble  and then i wake up. Or else i get the urge to urinate and i wake up . i cant fall asleep after that. In a period of 1 hour i fall asleep and wake up like 6 times. I visited a doctor , he said it might be due to gastritis and gave me some tablets because of whicj im able to sleep atleast for 5 or 6 hours continously. After that i cant sleep continously. I had an hiv exposure 8 years back when i was 12. Last year i tested negative on tridot , western blot and pcr. Im worried i might still have hiv and that is causing this problem . Is this hiv related sleep apnea?
