Chamomile and Valerian root come to mind.
There is a tea I used to drink, let me see if I can find it... Yes!!

If you scroll down the page, you'll see "What's in this tea," and you can hover your cursor over the question mark (upper right corner of each picture) to see what purpose each one serves. There are also fancy arrows ... < and > ... which will switch the page to the rest of the ingredients. (I thought they were just a pretty border at first!! .)
I also clicked "View all ingredients" - I thought it would take me to a list of ingredients for that tea, which would be easier than clicking the arrows - but it takes you to a list of everything they use in ALL of their teas.
Disclaimer: Although that tea does taste wonderful, , I am not necessarily promoting the purchase of their product. For someone who can make a hot sauce to set fire to the devil, using a list of ingredients to make a tea should be an easy task!
BigC You really should try and see what works for you. We can literally see your nerves darting in your brain with light bulbs...
