Just thought I'd pop in and say hi.. I'm on the 5th day of quitting cold turkey and it's horrible, I had lots of hot flashes on the second day and I've had a headache for the past few days but today.. I feel terrible, my headache has intensified, I feel nauseous, and heartburn? Anyone else get heartburn? Dizzy as well.. I'm tired and fed up.. Just wanted to compare this to other people's experiences to check it's just normal. On the plus side though I haven't wanted a cig all day cause I've felt like poop, lol.
