It' been going on for a bit now he seems to have a complete lack of stamina. For instance we were in town yesterday for under an hour and once I had done what i needed to do I had planned to go and try one of the new fast food places he was too tired at work he and I are working on a project (with no time pressure) he often says he's too tired to do any work at parties etc he needs to leave at midnight or earlier because even if he has a Red Bull he still feels tired is there any supplements that or anything that could help I was thinking of something like those gels you sometimes see tennis players eat on court but I'm not sure if he'd go for it them can you guys suggest anything?
