2 Weeks Ago I Had A Strange Flu Like Symptoms,

2 weeks ago I had a strange flu like symptoms, achy muscles fever...lasted for 48hrs off and on. then it went away. then I had a bit of vertigo and that subsided but then it left me with this like stress area between my eyes kinda like when you've been on computer for long time and you have a stress area at your forehead. I get a full nites rest but then I feel like I didn't get enough... like I want to get a COMPLETE nites rest and feel strong and envigorated in the morning. this thing just kinda lingers... I bought some liquid B12 and take my powdered vitamins....it helps slightly
