I stopped using Kava a long time ago for the same reason. Here's part of an article about sleep aids that mentions Lemon Balm. I would go with the Lemon Balm, also Skullcap is effective for anxiety/stress.
Three Plants to Promote Peaceful Slumber
German Chamomile � (Matricaria recutita)
You can find bags of chamomile on almost every supermarket shelf, and
we have probably all used it at one time or another. According to
leading herbalist David Hoffman, chamomile is probably the most
widely used relaxing nervine herb in the world. Although the
attractive flowers of this herb can have a wide range of health uses,
it is primarily used for rest and relaxation. There are several types
of herb called `chamomile,' but it is the German variety that is used
for tea. The other kind, called Roman chamomile, has similar
properties but is bitter and is used primarily for digestive upsets.
The mildly flavored, pleasant-tasting German chamomile tea combines
easily with other relaxing herbs. Chamomile is wonderful to have late
at night, but it can also be safely used in the day to ease stress
and tension. Since chamomile is gentle and effective, it is the first
herb to try for sleep disturbances.
How to Use: One teabag steeped for about 15 minutes in 8oz (one cup)
of just-boiled water. Or, two teaspoons of loose dried tea. Chamomile
is an easy kitchen herb to grow, so for fresh tea, use a good
tablespoon. No matter whether the herb is fresh or dried, always
remember to cover your tea so that the medicinal volatile oils do not
evaporate with the steam. Sweeten with honey if desired.
If you prefer, a liquid extract, also known as a tincture, or
capsules can be used instead. Use approximately 1-1 and � teaspoons
of the extract or two to three capsules.
Lemon Balm � (Melissa officinalis)
Although lemon balm may not be as well known as other herbs, it is no
less remarkable in its sleep-enhancing abilities. Its pungent lemony-
scent is tension relieving by itself. Used since the seventeenth
century when it was known simply as balm, this herb is great for
helping to relieve stress and anxiety, which in turn helps people to
sleep better. Research in Germany has shown that a key compound in
lemon balm, the volatile oils, calms the central nervous system.
How to Use:
Lemon Balm makes a great-tasting tea and is also effective when taken
in pill or extract form. Take 1 or 2 teaspoons of extract and two or
three capsules. For the tea, use two teaspoons dried herb to one cup
of just-boiled water and let steep for 15 minutes
Passionflower - (Passiflora incarnata)
Don't let the name mislead you � passionflower has nothing do to with
passion, and everything to do with sleep. This herb, which is native
to the southern United States, has been used for over 200 years for
its sedating and tranquilizing properties. One of the great
characteristics of passionflower is that it will help you sleep
without giving you the groggy feeling that is typical of many
How to Use: This herb can be drunk as a tea in the evening (one or
two cups, prepared as described above.) A tincture is also effective �
one to two teaspoons, or two or three capsules.
These herbs have a long history of use as gentle but effective sleep-
inducers. Their versatility means that you can combine all three in a
tasty tea, or you can choose to try pills or tinctures one by one to
find out what is most effective. Whatever herbs you decide to use,
hopefully you'll soon be sleeping sounder, longer and more
