There are a lot of symptoms during menopause and peri. Hormonal shifts cause mood swings. For me, my thermostat doesn't work so well at night, I go from hot to cold back and forth. There are a lot of natural remedies. Phytoestrogens can help. Eating organic soy for example, or taking wild yam supplements to help balance hormone levels naturally. B vitamins are a must for peri and menopausal women as is Vit D.
