If at all Nando's STD story was true, it looks like it's worsening and he's having hard time to sleep which has led him to asking for stronger sleeping pills.
Last week Nando was ill down on bed and we had no clue on what was eating him up not until he talked about being infected with Chlamydia by Selly. If our assumptions from his words are true, it could have been this infection that put him down and he has not yet recovered.
