Frumpy
As JWN says, how to read the stomach pains depends on how much of what you were drinking. If it was two bottles of wine or 8 pints of beer a day (or less) then you have, not to put too fine a point on it, just got the shits or some such related ailment. By stopping drinking you have, essentially, recalibrated your digestive system and it will take a little while to straighten out.
Or you may have got a bug from being run down.
If you were drinking more than half a litre of spirits a day, or any "non-standard" drinks (mouthwash, surgical spirits, shoepolish, bay rum, Brasso filtered through sliced bread)then you may have a serious health issue.
Just a rule of thumb - go with your instinct.
As regards the craving, if you are five days off the drink, the "craving" will be mental if and when it comes back.
That means you can beat it if your head is in the right place.
There are all sorts of ways to gget your head in the right place - my preferred way is AA but there are others.
The important point is that, now you have broken the cycle, there is no need to believe you are at alcohol's beck and call any more.
The only mistake to avoid (and beware, it is a common one) is to assume that, because you have "controlled" your drinking by complete abstinence, you can in the future "control" it by drinking a bit less or by starting and stopping or otherwise "moderating" your consumption.
I'm afraid that it just doesn't work like that, any more than you can jump off a cliff and stop half way down - most of us have found, often the hard way, that you are either on solid ground or in freefall.
