What Causes Dizziness, Fainting And Tiredness?

Hello



I've just been to the doctors for dizziness, fainting, head rush everytime i get up and constant tiredness. she said it may be the effects of the sertraline i'm on so try to keep hydrated and eat nutritious foods. i already do this and my tablets aren't due to stop for at least another 6 months! she read my blood pressure and it was 95/96 or something like that??? i can't remember exact digits. in other words it was low however she said she had no magic answer and i hate feeling like this. i have two active toddlers to look after and their mummy's almost passing out!
