To all that get ulcers:
Buy a bottle, over the counter, of Lysine 500mg. Very cheap and available in any drugstore. This will work both for "cold sores" on the lip or ulcers in the mouth.
There are two ways to do this.
1. If you get ulcers on a regular basis, take 1 tablet every morning (as a preventive) and you'll find that you get less of them or possibly none at all. If one happens to sneak through, and you feel a tingling or some other early sign, then take two tabs in the morning and 2 tabs at night until the ulcer goes away. You should notice that if in fact you get one every so often, they will not last as long by taking the 4 a day.
2. If you don't get them often, you can wait until you feel an early warning sign, and then start the 2 in the morning and 2 in the evening.
I'd love to hear from anyone that finds this helpful. I've been recommending this to my patients for over 30 years.
