Yes keep looking for sure, i was forever tired a long time before the PN struck,
I was just putting it down to the long hours of driving in my work, but not long after i started taken multi B & B12 it completely changed everything so i must have been running on empty beforehand :)
You have probably been asked this question, but anyway if you haven't, have you had your b12 tested ?
