Hello MaryG
That's useful to know that it's fine carrying it in your hand luggage. I am so paranoid about it getting lost on holiday I might get DH to carry some and my children

We are nowhere near the border unfortunately. It does seem silly that you can buy it so casually OTC in Spain, but not here.
As to hormonal anxiety/depression both Prof Studd and his colleague (can't remember his name) both said that 3-4 pumps were needed to alleviate depression and anxiety. But whether that's because 4 pumps suppresses hormonal fluctuations which cause anxiety, or whether it gives you the necessary oestrogen boost to improve your mood I don't know?
Last week I had a couple of dodgy days on day 6-7 of taking 100mg Utrogestan, presumably reacting to it? But last month I had no dodgy days at all when taking Utro.
