When I first started CAP on azithromycin and doxycycline I had to keep food in my stomach at all times because it was like some bottomless hunger pit. My stomach NEEDED food lol. It was mostly about my stomach then. After a few months that got somewhat better.
Now just recently doing the flagyl (consistent) and I already had to lower the dose to 250mg a day, I'm having some major episodes that are like when your blood sugar drops. You feel a bit sick, you start to shake, and generally you know you need food or sugar. Standing up waiting in line at the grocery store was interesting today.
