Can you get some medical assistance to help you detox? Hell, call 911 if you have to.
I don't think it's necessary for you to have to explain yourself and why you haven't posted here since December. You're here now and need help.
Please know that each day you remain sober while feeling like sh!t will be one day more that your body is readjusting. The physical sh!t feeling is temporary and will get better.
Continue to pick up a drink and you will feel like this over and over and over.
I detoxed like you're doing right now, alone, was in bed for a week and spent none of it peacefully sleeping, but my body did adjust and I began feeling really good.
You might want medical assistance; you might not - either way, know that what you're going through right now is one day closer to your body recovering. Stay hydrated and rest, rest, rest. We do recover and we're here for you. Sending good thoughts your way.
