I'm not a doctor so I can't tell you that what you are feeling is post accute withdrawals or not.
I think you owe it to yourself to see a Dr., just to reassure yourself. You could have something as simple as low blood sugar going on. I think if there was anything else going on, they surely would have noticed it in the blood work they have done everytime you were in the hospital. Everytime someone sets foot in the hospital, you know they take a mess of blood and this is where if anything else was going on would have showed up.
Our disease wants us back. It will try anything to pull you back into it's grip and I think yours is trying to play on your fears by having you think something else is going on. It wants you to run back to the security blanket you used for so long, alcohol.
Hang in there, congratulations on your Sober time and keep us updated!
Peace,
Judy
