Hi everyone, my name is samira and I'm a 19 year old female. The start of August 2017 I began having sleeping problems. I thought it was my sleeping pattern which I missed up and was excited to finally sleep the night after, again, nothing. This continued for weeks and it's almost September now. I finally went to the doctor explained everything and they took a blood test. Also guys I go gym and my diet is decent. A week later they said I has Vitamin D deficiency and low iron and prescribed me pills which I assume is vitamin pills. However, I don't feel like that's the problem, I feel like there's something else. Has this ever happened to anyone and can vitamin d or low iron cause insomnia ???
