HI, i got up like at 11, had a fag, half an hour later... had another one... came down stairs, got some crisps and a bar of chocolate and then come upstairs and had another fag... i came downstairs and made a toastie and then was drying up and went really dizzy and my vision went really bright like i was looking into the sun and i got a headache and felt sick and could see white dots. what is this?
