Hi Ali51
I personally think it's too much. I get exactly the same if I go over board. I'm either crying all day, or depressed and angry, I've even been high on too much, like I've had an injection of energy. Then crash and get low! ......Maybe you should drop it by half a pump, not easy as it's a pump, but sometimes even the smallest amount will make a difference especially if your sensitive to it. it's all trial and error really.
As for it settling down, I don't really know, I've always dropped mine as I couldn't stand the effects it was giving me, I've settled on pills now, Femoston, and some days are hard, some are ok, so although not perfect, it's better than how I was before, and the prog in it suits me.
I'm hoping someone will be on with more knowledge than me to advise you. So hang tight.
