From 23rd sept night am badly nauseous. This nausea starts after dinner and goes on till midnight resulting in no sleep. Got cold and headache on 24th evening. Every midnight, around 3-4am I take a sinarest tablet and that helps me to sleep. Now cold has vanished but headache on the right side and nausea is constant every night. Have become physically very weak and feel feverish but the temperature is nornal. Feel constipated as well.
