I suppose we are here to tell you that life does get a bit better after a while! Joint pains - I had them, and unfortunately they turned into early arthritis. My shoulder went first, then fingers, then right hip, base of thumb, and so on. Some of the fingers recovered, the horrible night-time stabbing stopped but at the time, apart from taking painkillers, I found that fingerless gloves at bedtime (particularly in cold and rainy weather) plus bedsocks were the only pain relief that worked. As the rest of me was usually naked due to night-time sweats I must have looked SO sexy! However, I do think that some were due to perimenopause and others to arthritis, as a few pains have ceased.
Periods usually stop at around 52 yrs, mine stopped a few years ago.
Sleeplessness was a problem from around 40 onwards, together with the pains. I started to take sleeping tablets, just to keep my sanity. Now I find that as long as I wear a silk sleep mask I am ok, but having a late child also plays havoc with your bladder, which tends to wake you for loo trips.
So, now picture gloves, socks and sleep mask - three
Sex-life - nil.
I am now interested again, but DBH, not so much. So I have been reading articles about low testosterone and the male menopause instead lately, and it really does seem that they go through a similar experience to us, it's just not as noticeable as they are usually grumpier anyway. 
I love not having periods, the freedom from them is just wonderful, it's almost worth the increased rapidity with which wrinkles develop at this stage of our lives.
Heart palpitations - just stopping now. (late 50s)
Shifting weight - incredibly hard. You have to completely change your way of eating and with added joint pain, exercise becomes harder for many of us. I had to stop going to the gym, swimming - anything repetitive had to go. Elasticity disappears rapidly, as does shock absorption in knees etc.
The anxiety has almost gone, I lived on St.John's Wort for years, it was wonderful. I can thoroughly recommend it. I stopped taking it a few months ago, after a few trial efforts.
I spent a fortune on supplements over the years and I can't say that any of them worked particularly apart from fish oil, which did seem to ease the joints. Ibuprofen on bad nights.
For the hot flushes - sorry, cut back on alcohol and cream. The difference is incredible. So it's lovely to be able to drink again, and have a little cream on my strawberries. When you are in your mid 40s and go to a party, you look at people there and instantly your attention is drawn to the reddest face - always some poor woman. My MiL when I met her always used to look as if she had just got out of the shower, she was so bad.
