Hi, I am a university student. I strongly believe I suffer from insomnia, this is affecting me negatively in a lot of different ways, I feel sleepy and unable to sleep, headaches, nausea, loss of appetite, extreme sweet/salty food cravings, feverish, lack of focus and horrible span of attention. Having gone to the doctor, and getting blood work done, the only thing they pointed out was that I was severely deficient in B12 and Iron, and told me to start taking supplements. I haven't been regular in that, but I do not think they are related to my sleeplessness. Please advise as to how I should get around this problem. It is starting to show in my work and I do not want to slip any more. Thank you
