Lack of focus
I was having long term vitamin b12 and vitamin d deficiency, I didn't knew about it until I started feeling tired, foggy and sleepy all the time since few years. I recently fixed all of my deficiencies and my blood reports are all good. But I was unable to function properly so my doctor gave me flunil 20mg so that my brain can stabilise. I am at day 46 on flunil 20mg, I can function normally but I can't do tasks which requires heavy focus and memory sharpness. When I started studying my brain just feels stuck and it makes me tired and sleepy.
