How do I get rid of Oral Herpes?!??!!?!?

Ok, so I 1st got oral herpes last Christmas and it has been coming back every to months and as it happens I have it right now. I went to the doctors and they gave me Valtrex. I had a severe allergic reaction to it. So I was taken off of it and was given abreva which doesn't work worth crap. The doctor told me there is only one other thing but, it is like a sister to Valtrex and it has 80% of the same ingredients and there is no way that I'm taking that because I don't want another bad reaction. So I'm screwed. I tried hot and cold compresses and pounded the vitamin C to me. It still won't leave it's been at least a good few weeks. I'm getting very ticked off. I only get a few hours of sleep because of it's oozing and gross crust I feel on my face. To make it even better it has spread from my lips to above the lip on my chin and developing on my cheek. I wash my hands about 1,000 times a day. NEED HELP PLEASE!
