When I wake up, my head feels very heavy. There is a slight pain too. When I go in sunlight, my left eye starts straining and I have a headache. I'm wearing spectacles. But sunlight stings my left eye. It feels I have less control in my left eye. My throat is riddled with mucous, and I have to gargle often to remove. After waking up, my mouth is extremely dry, and sometime a bad taste is left afterwards. If I do breakfast early in the morning, I'll have a bowel movement again. If I don't eat, it is fine. I feel tired often. I'm slightly overweight.
