I had to take Doxycycline for 3 weeks last August when a tick bite I had developed the classic "bulls eye"... a sign of Lyme disease. Everything went well for the first 10 days then I started getting kind of nervous and couldn't sleep well at night. I was constantly starving, really ravenous and had to eat constantly otherwise the nausea got worse. I was glad when I was finally able to stop taking the meds, BUT then after 24 hours I became depressed and really fuzzy in my head and disoriented. This lasted for another 2-4 days. I'm feeling much better now, but I have noticed that I'm just a lot more sensitive to other stimulants...coffee, sugar, alcohol, chocolate. I know I have a few other allergies, hay fever, food allergies etc. I was just wondering, does anyone else out there who has had a negative reaction to doxy have any other allergies or intolerances, or asthma? How much sugar, either in the form of sweets or alcohol do you usually consume? Daily, weekly, monthly...none at all? Feedback would be greatly appreciated. I would like to get to the root of this problem.
