jess - yes, flushes can go on for quite a few years but many women find they settle anywhere between 6 months to 5 years.
Skin will become more dry and itchy, joints may ache more, lack of energy, loss of libido, poor sleep etc. - the list goes on and on. We are all different so post menopausal symptoms will vary - some women sail through and carry on as if nothing has changed. Problems with vaginal dryness and discomfort is probably more common than we think but this is something that many women don't like to discuss so will often put up with because they are embarrassed to discuss this with their doctors. Problems with bladder function and UTIs is another area that is quite prevalent. A good diet and sensible exercise can help to alleviate many symptoms and if that doesn't help then HRT is the only real option.
Oestrogen deficiency can cause all sorts of problems but I wouldn't look for problems - just try to stay healthy.
