melatonin helps greatly with sleep. Not so much in the getting to sleep, but in improving the quality of the sleep you do get.
As for sleep medications, there are LOTS. You can try benadryl which is what is in most of the 'pm' OTC sleep medications like tylenol pm, etc... You can also try other rx medications. Ambien and lunesta are fairly new medications and the problem is NOT new so there are many older medications. Be aware that lunesta can leave a nasty taste in your mouth when you wake up. Takes hours to get rid of it for me, but I don't know if that is normal.
Tricyclic antidepressants are an older class of medications that MANY people used for years to deal with sleep issues. They also help prevent migraines for some people, so maybe a two-fer if you have those. Amitryptiline (elavil is the brand name) and doxepin are two of them. These are also used to help deal with some chronic pain conditions. For sleep problems, some people do well taking them 1/2 hr before bed, some need to take them 1-2 hrs before bed. You just don't know unless you try and know to tinker with that.
Benzodiazipines like xanax, valium, temazepam, lorazepam, etc... can be very effective for sleep. Be aware that valium WILL cause depression if you take it for more than a few weeks at a time. it is one of the most common side effects according to every doctor that I have ever spoken to about it. this is why most docs will give you temazepam or lorazepam because they don't seem to do that. Alprazolam (xanax) is in your body a very short time and so isn't as great as a sleep medication for some people. It also has the highest risk of addiction/dependency.
trazodone is a tricyclic a/d like elavil and there are others in that category.
Remeron (mirtazipine) is also used for sleep issues, as are muscle relaxers if you also have muscle problems.
I don't know if you drink herbal tea, but Celestial Seasonings makes a tea called Tension Tamer that can be a big help in relaxing you before bedtime. Right after my hysterectomy when I was plunged into surgical menopause this was a huge blessing. I would drink a cup or two before bedtime as part of a routine and it was a big help. I also had to cut out caffeine by about 4 pm or I would be up all night long.
Sleep hygiene can be a problem with the challenges of menopause, but it is important too pay attention to it. You might try googling sleep hygiene to remind yourself what good sleep hygiene is (most people have no real clue according to the sleep doctors) and try to see if some changes in your sleep hygiene might help.
