How are you managing the headaches?
I have just gone up to 4mg and the headaches have been dibilitating. I am prone to headaches anyway but I've had one pretty much non-stop since increasing my dose 4 days ago. I don't think I'm dehydrated as I drink at least 2 litres of water a day, but I have obviously been eating less.
Ibuprofen isn't touching the headaches so is there anything else that you have found helps?
