First of all, having a healthy lifestyle and diet that suits you will greatly reduce stress and therefore outbreaks. If you are allergic or sensitive to wheat, you shouldn't be eating oats either as they usually have gluten in them. I'm completely gluten free. Look into eating paleo or just eating A LOT of fruits/veggies/protein.
Taking vitamins and supplements is a great idea, the l-lysine as well as vit c and b vitamins (especially b12 cause it's just awesome and if you're allergic to wheat it may have damaged your digestive system and leads to vitamin deficiencies such as b12, folate, and vitamin d, so taking good vitamins is a must)
There are antivirals you can take during outbreaks if they are uncomfortable or painful. I found for myself the first 2 years was the absolute worst, and after a while you either stop having them or they become less frequent. If you have questions, talk to a doctor or health nurse. Some cities have open clinics for patients with std's etc to come in for testing and to ask questions.
I use an antiviral topical cream which has worked well to minimize discomfort. I don't like to take medications, I'd rather prevent than treat. Don't worry too much because that can make it worse, and living with herpes is really not as big a deal as people make it out to be.
