The past two weeks I have been constipated and unable to sleep more than 4 hours a night. I am wondering if these could be related. I have been trying to eat fruits and whole grain breads more often. I tried taking milk of magnesia yesterday, but with no success. As far as my sleeping, I can fall asleep fine, but wake up after about 4 hours and can't fall back asleep. I am a 24 year old female graduate student in biochemistry, so I work 12+ hours a day and usually on my feet at least half of time (been doing for years, so I doubt this is stress-related). Though I do not get extra excercise, I usually feel exhausted by the day's end and cherish my sleeping hours. Other than the birth control, Yasmin, I take no medications.
