Nicksy, If you take an antiandrogen without taking Estrogen it can lead to bone density problems. Anyone who has very low hormone levels is in danger of losing bone density-that is one reason why it is so important to have your hormone levels monitored.
As far as being forgetful, before I got on Estrogen I was a scatterbrained basket-case. After that I was fine and my skin is dryer now so I use moisturizers every day.
