I don't see anything terribly wrong with tea. If you're cutting it out because you want to be free of the shackles of caffeine, or for other personal reasons, a replacement I like is rooibos. I know you said you aren't crazy about herbal tea, but rooibos is warm and rich. It's really nice with heavy cream or coconut milk, and on it's own. It's often sold in chai or spice blends that are nice too.

here's what wikipedia says about it's 'health benefits':

Rooibos is becoming more popular in Western countries, particularly among health-conscious consumers, due to its high level of antioxidants such as aspalathin and nothofagin, its lack of caffeine, and its low tannin levels compared to fully oxidized black tea or unoxidized green tea leaves. Rooibos also contains a number of phenolic compounds, including flavanols, flavones, flavanones, and dihydrochalcones.

Rooibos is purported to assist with nervous tension, allergies and digestive problems.

Traditional medicinal uses of rooibos in South Africa include alleviating infantile colic, allergies, asthma and dermatological problems

You could drink weak bone broth, such as chicken broth. It is very comforting and nutritious.

I add heavy cream to my tea or coffee which makes it delicious and satisfying. I wouldn't worry too much about a little tea, as long as it isn't laced with sugar.

I love the warmth of a hot drink too. I haven't bothered to find a substitute for coffee since I haven't had any issues with drinking it. If tea isn't causing you problems, I don't think there's a need to cut it from your diet. Use heavy cream or coconut milk instead of milk. I've gotten used to not using sweetener.

I know what you mean about the ritual. :~) I guess you don't want to use stevia? I use a tiny bit of stevia and coconut milk (about 1/4 cup) in my coffee and black tea. I also drink lots of iced tea made from half green and half black tea, with lemon juice and stevia. I try not to use much of the stevia. You could make black tea with coconut milk and cinnamon in it (no sweetener) - that is pretty yummy.

Tea + heavy cream. Don't stop drinking it, just start drinking it plain. Green tea is excellent also. I love oolong :D

Aromatic waters are popular where I live. You can literally add anything you want. put in a small tea pot a variety of fresh things like spearmint, lemongrass, cinnamon, cut fruit like strawberries, apple, etc. (just a berry and a thin slice or two of apple will do). pour the hot water on it and let it heat a few minutes thru.

The fruit gives some sweetness and the herbs add flavor!!

I used to have 2 sugars in my tea and coffee. If you cut it out, after about 2 months you will forget you ever have sugar at all. you will never look back. now i actually know what coffee tastes like. i can also now appreciate dark chocolate, because i dont have such a sweet tooth.

A yummy treat for me: roobois chai(EcoTeas) with coconut milk and a little stevia...hot or iced=delicious!

If you're adding milk for the sweetness factor and you're wanting to cut the dairy you could try using a little raw local honey.

Apple Cider Vinegar! I carry a dropper bottle with me and add some to hot or cold water when the plain stuff just won't do.

Also..

You can boil some sliced ginger root (for, say, 30-60 minutes), and then keep the strained liquid in a dropper bottle. This is a lovely kick to water. Add some stevia if you like and you've got a spicy sweet concoction.

Whatever you do, don't use xylitol if you drink more than a cup. I was sweetening my iced tea as I drank it all day, and thought I had a mild case of food poisoning.

I believe that tea is completely Paleo. Maybe find a better quality tea that tastes amazing black? Numi Earl Grey is like that. Amazon has a great price on a case, but you should try a box from Whole Foods to see if you like it first. I was amazed at how smooth and flavorful it was.

I make a pretty mean iced green tea that taste even better than sweet tea (I live in the South).

1/2 tsp Matcha green tea (asian market $7 for 3 month supply).

1 tsp local honey

ice cubes

H2O

You can blend in berry flavor to give it more Paleozing.

Use Acai powder or gojii berry powder.

Hot (warm) chocolate with cacao powder w/ or without berry zing.

Sometimes i drink hibiscus tea, but mostly its green tea with no flavoring, or maybe with a lemon if i have one by the counter sliced for salad.

you ever try turmeric boiled in water? I like turmeric and ginger a lot. Lots of flavor, nothing like herbal teas at all. As to making it portable, that concentrate idea sounds pretty good. Alternatively, just travel with a thermos.

note: this is not sweet, and that may or may not work for you without adding something. Personally, I can't stand stevia (and I used to grow and market it as a Peace Corps volunteer!).
