Well, I'm not sure now whether it was the drugs (man!) or whether it was just something which would've happened anyway - the day I started the Edronax was the same day as the first day of my period, so I may just have been having a low-BP day anyway. Certainly I added an iron supplement to the mix yesterday, and didn't get anywhere near as dizzy as I had been, so I'm thinking it might have been just something to do with the normal quirks and foibles of my body rather than the addition of a new anti-depressant into the mix. We shall see how things go when I add the other half a tab on Sunday afternoon.
