Hi kmp, welcome to the board!
A bulls-eye rash can occur at any time and anywhere on the body (not just in the location of the bite). Although only about 50% of people who have Lyme ever get a rash, a bulls-eye rash is a definite sign of Lyme disease. If your rash comes back, be sure to get photos of it. It is important documentation. Place something near it, like a coin or ruler, to give it size definition.
Below is a Lyme symptom list. You can have any combination of symptoms.
As you can see, the last symptom is exaggerated symptoms from alcohol. Which test did you have done? It is my understandind the ELISA or titer is the least reliable test and the one most doctors run first.
When Lyme is a possibility, it is very important to see a knowledgeable doctor. Many doctors do not understand Lyme and treat with outdated protocols. No test is completely reliable, and results can vary by lab. Besides Lyme, ticks can also transmit several co-infections including Babesiosis, two types of Ehrlichiosis (HME & HGE), Bartonella, and Mycoplasma. Many people who have Lyme are co-infected. It may affect treatment choice and progress. It is important to be tested for these by a Lyme reputable lab such as IgeneX in Palo Alto, CA.

It is also important to learn as much as possible. I recommend reading Dr. Joseph Burrascano's 2008 Diagnostic Hints and Treatment Guidelines For Lyme and Other Tick Borne Illnesses at http://www.ilads.org/lyme_disease/B_guidelines_12_17_08.pdf He is one of the top Lyme doctors in the country, and many Lyme doctors follow his protocols. I also recommend the books "Everything You Need To Know about Lyme Disease Second Edition" by Karen Vanderhoof-Forschner and "The Lyme Disease Solution" by Kenneth B. Singleton M.D.
I hope you can get answers soon.
