Hi dm, and welcome to the forum!
There certainly are people on here at various stages of "wellness!" Great that your meds are helping, but it's like walking a tightrope until you figure out what's triggering your mast cells. There can be both environmental and food triggers, and while there are some triggers a lot of us have in common, there are always individual ones, too.
Keeping a food and environment symptom diary might help you become more aware of what's causing your symptoms. Here are some examples of common things, other than foods, that can cause many people to flare:
Stress
Heat or cold
Smells, scents, and perfumes, both artificial and natural
Toiletries, such as soaps, shampoos, conditioners, make-up, shaving creams, etc.
Environmental true allergens, such as pollen and mold
Dehydration (even mild)
Cleaning products
Viral or bacterial infections
Medicines (However, some medicines in each category are more likely to be tolerated.)
Anesthetics
Antibiotics
Muscle Relaxers
Preservatives, fillers, and additives sometimes used in medicines
Artificial colors and/or flavors used in meds
In keeping your diary, consider what you did, ate, and felt before your symptoms. Remember that reactions can be delayed, so what you ate last night can affect you this morning. Note anything stressful that happened that day. Think about what you ate, how you felt, and where you were before the symptoms started.
If you have a headache or brain fog after a trip to the grocery store, and you remember you walked down the detergent aisle, it could be scents or perfumes that caused your symptoms. Is it pollen season and you have IgE allergies to pollen? Did you have symptoms an hour after cleaning the bathroom or vacuuming?
People have felt better after removing all scented products from their houses, as well as strong smelling chemical cleaners. If there are true allergies, removing everything in the house that is an allergen to you might help. Switch to unscented personal care products. Use none or only unscented fabric softeners and laundry detergents that are recommended for people with allergies, even though you might not have true allergies.
Unless you have aggressive disease, and you don't seem to, daily medicines are the primary treatment. Some people use a variety of anti-inflammatory, probiotic, and other supplements. If you're still having bothersome or dangerous symptoms, you might need to increase your meds or add something. If you want to post what you take, how much, and what time of day, people will respond. Most of us take H1 and H2 antihistamines at least twice a day. Some also take PPIs, Gastrocrom or ketotifen, steroids, and others in order to keep symptoms at bay.
Have you tried an elimination diet? Some people are helped by the low histamine diet. You can find one at:
www.urticaria.thunderworksinc.com/pages/lowhistamine.htm If you try it for a month or so, you can then add back foods (one every other day) to see what causes symptoms to worsen.
Some foods cause direct histamine release from the mast cells. Others contain a lot of histamine, either naturally or due to poor storage. Still others are processed with chemicals, spices, additives, preservatives, etc. Leftover meats are particularly high in histamine. Most alcoholic drinks are, too. If you are sensitive to latex or ragweed, find out which foods cross-react with those things. You'll find lots of posts here that talk about food problems and solutions.
If you want to post your meds list, people will look it over and see if it seems to be adequate for your symptoms.
