I just wanted to add this just in case some searches this thread later... I went to see the specialist and he was very good. I hope the headaches go away soon. it is a common side effect and Inderal is a safe preventive. so if the headaches don't go away after week 20 I might try it. you take it twice a day for 3 weeks and then they should go away. but you still need to take panadol because its not a painkiller. it work in the blood vessels in your brain so thats why its a migraine preventive apparently it has been around since the 50's and safely used in pregnant women for a long time. He also said in some women oranges & chocolate can cause migranies. I have really been craving oranges (they are so juicy) and eating like 2 or 3 a day so I am going to give them a break for a few weeks to see if they go away. xx Mel
