Hi matty. How long will you be on Doxy?
I don't know if you are aware, but there are some important tips about taking Doxy. Do not have any diary, magnesium, or iron products within two hours of taking it or it will not be absorbed properly. Is it making you nauseous? It can cause this. Try eating something substantial and non-dairy before taking it. When I took Doxy, what helped me was to eat some kind of sandwich with protein. Avoid the sun. You can get a severe burn in minutes even when wearing sunscreen. 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.
When taking antibiotics, it is important to take high-quality acidophilus capsules. They replace the good bacteria and help prevent yeast overgrowth. The best ones to get are refrigerated and have a high culture count. Most healthfood stores carry them. This may help with some stomach issues. Wait at least two hours after taking the antibiotic to take the acidophilus.
Antibiotics can stay in your system for a few days after you stop taking them. Call your pharmacist to find out how long Doxy can.
I hope this helps!
