For the passed month I have been feeling really dizzy so I been making sure to drink lots of water. Also here and there I have been feeling like I'm going to pass out even when I'm led in bed which scares the life out of me. I'm not sure what's going on. My last venesection was the end of November I'm not due my next until end of February. I've noticed the tiredness is getting worse along with the rest of the symptoms you get with PV . I'm still trying g to get my head round it all . Just feel like giving up at the moment . Hoping you guys can help .
