My question is: I've been trying to quit smoking for a while but yesterday I had exams so I smoked alot (14), then had like 4 donuts (too much sugar i'm guessing) then got back home after a very long and tiring day. I had this huge vertigo in my head, I literally lost balance as I walked to the kitchen twice not once. It's a feeling I never had before and scared me to death. While trying to sleep last night my heart bpm was around 100 which is high I think. I woke up today all puffed up and the vertigo is gone but came back again 6 hours (which is now) after I woke up, I've had no cigarettes so far (trying to quit cold turkey I guess). I fear I have a tumor in my head (no headaches though but some tension in my shoulders) or had a stroke last night. This emptiness in my head like something is pulling my head backwards towards the ceiling is frightening. I'm extremely scared, please tell me what to do. Thanks for your effort and advice.
