Lack of Sleep (Hi, Doc)

On my 6th mo. now For the past two weeks, may insomnia ata ako or hirap lang makahanap ng tulog. I normally sleep at 1am or minsan 2am. Then I usually wake up at 8 am. Natutulog din naman ako sa araw like 2-4 hrs during the day. I read some articles and sabi pede daw mag cause ng high bp and gestational diabetes and lack of sleep. Huhuhu true kaya ito? And any advice pano makahanap ng sleep? I have asthma kaya di din ako pede ng mga essential oils :( Salamat! :)
