Hi keeptrying,
Good for you on sticking to things since Sunday! Small steps, but in the right direction – keep it up.
I’ve had a few bad days – like you I had a headache for 3 days & was nodding off on the sofa (stress at work, and not drinking enough) and had to drink like a fish (painkillers didn’t help). Weight went up slightly – only now that I’ve got back to “normality” has the weight started coming off again. Although I’ve not experienced the shakiness, etc that you seem to be suffering.
Perhaps it is your body still being in a state of adjustment – it’s not punishing you, it’s just fighting your new regime because it’s not getting all those bad things it has grown used to. If you give in and have a binge you will be going back to square one and then have to go through it all again when you resume. Maybe this time, try and tough it out (gnaw on a chair leg if you have to π ) – once you are through the worst of it then it should be easier to cope with if it happens again.
You can do it!
