[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. You may have Sleep Related Disorder (SRD). You are having many risk factors for SRD like1. COPD2. Hypertension3. Diabetes4. Mild stroke etc. So better to get done Sleep study to rule out RDS. If sleep study is normal than consult neurologist as black-outs in night can be due to TIA (transient ischemic attack) and high BP, diabetes, COPD and stroke can be the risk factors for TIA. So consult neurologist and discuss all these.
