Hi well come to HCM.
Nothing could have relation. with your smoking
.It seems you are having some serious
making you to smoke whole packet in single night which usually you do not.
That it self suggests sleep less night with severe anxiety. Temperature could be due
to some ifection adding to headache. You may take some paracetamol
,ad take good
sleep if needed may take some anxiolytic like alprazolam and if temperature persists
may consult your doctor for clinical examination and in case of need invetigation. Thanks
