ANSWER: I’ve heard of effects such as this from the changing moon before with those who follow nature-based paths, but I have never come across this as a witch thing before your question landed in my inbox. As my advice is always to check out physical world answers before magical, I did a quick google search and it seems to suggest this might be a health problem rather than an energy/intuitive thing. My suggestion is to make an appointment to go see your doctor and ask for their advice.
Bright blessings,
Sarah
