What are the Different Types of Withdrawal Symptoms?

I recently kicked caffeine due to heart palpitations and ectopic heart beat. I am suffering from migraines, sleeplessness, and worst of all I have been light headed/foggy for the last four days. It's been so bad I can't even do my job and have been burning vacation days just to get over these symptoms. I don't know when this will end, but I hope soon. I am also hoping it's not something serious like a brain tumor or even more heart problems.

I totally agree with Post 1. I'm five weeks into quitting smoking and share the same symptoms and others too such as crawly skin (itching) and panic attacks. Although the sweating has calmed, I still sweat a lot at night. I fear that I'm dying and should just smoke until I do. The brain is more powerful than you know.

It's funny to read how some say it's all in your head and I can see that for the most part it is, but if you haven't gone through it, sorry, you have no idea what you're talking about and it just doesn't stop by snapping your fingers. I'm hanging in and staying away from cigs. I just hope the side effects go away soon.

Addictions - whether they be to illicit drugs or even sugar - are not the same in any two given people. This is what troubles me about sites like this. You can't paint with a broad stroke what ails everyone who's going through addiction.

I find it insulting the way this page brushed off "psychological/emotional" symptoms as if they're entirely separate from physical ones. It's also highly likely that whomever wrote this was not a doctor (note the stock photo pic of the lady doctor and anonymous feel to the page).

I am on Day seven and not doing very well. Today has been nausea day. I keep having this burning pain in my arms, shoulder and sometimes my legs.

I'm a wreck because the body pains are wearing me down and causing me to be more anxious. Is this normal? My forearms feel like they have been sunburned, but my shoulders & arms are on fire! I don't know what to do.

I do not have any cravings because all these withdrawal symptoms are enough to scare me to death - I never want to smoke again! Is this normal for the symptoms to be so intense: headaches, body pain, cold chills, hot sweats, nausea, diarrhea and on and on it goes. I'm concerned that I'm dying!

I have serious bruising to my bones and muscles and quit smoking two weeks ago today, combined with potentially losing a very important personal relationship. Nothing comes easy for me but that's okay. any suggestions? Fatigue is really getting the best of me.

@turtlez - Coffee normally has more caffeine than Coke, that's why. When I go off of coffee, I get both migraines and feel really nauseous. anon93367 is a good example of how intense withdrawal can be and how they vary from person to person.

Oh, I do! Well, I mean, I actually drink too much Coca-Cola and soda. Whenever I don't drink (or "use" as you say), I get horrible headaches, even migraines as a form of withdrawal. I hear that that is common among caffeine drinkers.

Can't stand the taste of coffee, though people who drink it always seem to be more zippy than me, I wonder why that is?

anon93367 - Withdrawal symptoms are generally different for everyone. Most of it is based on how long you've "used" (so to speak) and how much you "use." Aside from that there are several other factors like overall lifestyle, type of eating habits and many other things.

I, myself, am addicted to caffeine, but have never tried quitting. Anyone else drink too much coffee out there?

Please don't lie to people about nicotine withdrawal. Five weeks after quitting cold-turkey and I'm still sweating profusely, suffering from horrible headaches and anxiety attacks, having trouble sleeping and having bad dreams.
