Hi newtothiss, welcome to the board!
How did you remove the tick? For future reference, please know the only safe way to remove a tick is with tweezers by grasping the mouthparts as close to the skin as possible and pulling straight back. Save the tick, it can be tested for disease at IgeneX Lab in Palo Alto, CA.

There are some important tips about taking Doxy. Do not have any dairy, magnesium, or iron products within two hours of taking it or it will not be absorbed properly. If it makes you nauseous, eat something substantial and non-dairy before taking it. Avoid the sun. You can get a severe burn in minutes even when wearing sunblock. Some people get burned knuckles from the sun coming into the car when they are driving, so I advise you to be extremely careful. Do not lay down for at least an hour after taking it, or you can ulcerate your esophagus. This is very painful. Drink a full glass of water when you take it for the same reason. Whenever you take antibiotics, make sure you take high-quality acidophilus at least two hours apart from the meds. This helps to replace the good bacteria and prevent yeast overgrowth. The best kind to get are refrigerated and have a high culture count. Most health food stores have them.
From what I understand, six weeks of the proper dose antibiotic is the minimum treatment time for an infection caught within two weeks of the bite. The antibiotics kill the bacteria when they are reproducing which is estimated at four weeks. Six weeks of treatment will cover one growth cycle. If symptoms are still present, further treatment is warranted. A longer infection needs longer treatment. Early infections are the easiest to cure. Getting the proper treatment now may reduce the chance of long-term complications.
Be aware of the Jarisch-Herxheimer Reaction (herx). Often when people who have Lyme take antibiotics, their symptoms get worse or they get new ones. When the antibiotics kill the bacteria, toxins are released making them feel worse. It can be scary when it happens, but it is a sign the antibiotics are working. This is probably why you feel worse. During treatment, it is important to document your symptoms daily. One way to do this is to list the main symptoms you have with a numerical rating of their severity from 1-10. Over time when you review this, you can see when your herxes occur and how you are responding to the meds.
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. He discusses antibiotics and doses starting on page 18. 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.
Good luck with your treatment.
