Hi. I'm sorry I have no advice, but I am interested in what you say.
I'm on my 6th pill trial... They all make me ill. I'm 44. 2 years ago I took agnus castus for 3 months and, like you, it was amazing, but I stopped because I was getting severe migraines and wasn't sure if connected, or not.
Can I ask why u were advised to have a break from it??? Is it worth persevering for longer with it???
