1. Acid Reflux (only the week before my period arrives) this leaves me with a one-sided sore throat for about a week? 2. Eyesight feels on/off worse 3. I have a narcissistic sibling who seems to ramp it up at Christmas. I just can't be bothered with it anymore. 4. Aching shoulders and neck. 5. Aching back. Week of ovulation and week before period only. 6. Chronic insomnia. Never being able to fall asleep easily.
