I had a cold with a bit of fever and sore throat for a few days some weeks ago, but this started before then. They did a 'tired all the time' screen on me which was for deficiencies, thyroid , blood sugar etc i think. I don't think I'm actually 'tired all the time', though, just 'asleep most of the time' :L most of the time I'm awake I don't feel too bad.I'm still on venlafaxine 225mg which I've been on for about a year now. I don't remember it causing extra tiredness when I first stated it. Thanks for the replies, guys.
