I m a 24 year old woman with a BMI of 15.9. I have lost weight due to a restricted diet (due to unhappiness during a year spent in Europe). I am not suffering from a typical eating disorder. I eat a good breakfast, a wholesome lunch and 1-2 snacks per day. I work out 2-4 evenings a week. However, I have a food OCD problem where for most nights a week I will only eat 2-3 slices of wholegrain seeded toast generously spread with nut butter, an apple, a banana and 4 chocolate brazil nuts for dinner. I also drink 3 cups of tea with dinner. I go to bed 1-2 hours later. I have been eating like this for several years, on and off, though I do break the cycle from time to time to go out for dinner etc. I experience night sweats and wake up very damp around the chest area. I know I need to work on breaking the cycle with my evening meal. However, I would like to know what is causing the night sweats so I can address this more quickly.
