Thanks for your replies! I've been taking 6-8 fish oil casules a day for years for rheumatoid arthritis but stopped when I couldn't swallow them due to severe morning sickness. I should be able to take them again now. I didn't even think about them.
I've been snacking on a lot of nuts but stopped a few days ago and since then my skin has been far less itchy!
I'll still need to find out about the safety of the Moo Goo as it does provide relief.
