A few POIS-patients say that they sleep bad when in POIS. And that the healing proces is faster when they take a nap or sleep aid. What if POIS causes a temporary sleep apnea? I am in a POIS like phase for 4 months now (without sex) and I sleep very bad. When I had sex the first night I sleep very bad. I always thought that was because of more tension on the joints and muscles. But what if it is apnea? I am thinking about doing an apnea test with equipment at home. The next day you bring the stuff back and they discuss the results with you. I can not have any sexual activity now because my gut just get better after being destroyed by antibiotics. The problem is that I get UTI and prostate infections after sex. So then I have to use antibiotics and I do not want that. Otherwise I could test it while in POIS.
