I have this issue too. I'll wake up between 7-9am but by 10:30 im yawning and feeling slightly tired throughout the day.
I dont even want to go out and party. I feel like I used to but I was probably sleeping till 10-12. There's times when im out drinking and I just feel tired so I get all quiet and unexcited because I just want to go to bed, girls have asked me if there is something wrong... im literally just tired im not interested or excited about the situation enough to talk.
I stayed in cincinnati three days, a few weekends ago, slept with this girl all three nights on the second night tho, I didnt want to have sex with her, I just wanted sleep(it was 4am but), she was offended asking me what happened how I could want to have sex with her last night and not this night, I just said I was tired as hell and didnt want to, she says "but your a guy" and I just said "yup... and this guys going to sleep".
I want to believe all these low-T commercials are bvll****,... but are they?
