I am low in both estrogen and progesterone, but can't take estrogen without taking progesterone. I have read that progesterone can cause problems with adrenals. I used to take progesterone for years then I quit and 6 weeks later I got insomnia and never got over it. I think it was suppressing my high cortisol or something. Now is progesterone the think to use for excitotoxcity or would it do more harm than good? Should I just not do hormones or look at herbals instead to help my lower hormones. Having lower hormones causes sleep to be poor too. I have CFS & virals too.
