This is some excellent advice. It’s the most positive step you can take right now. Joining meetings, chatting on TS, or with someone supportive helps with long term sobriety.
It seems like you have been heavily binge drinking spirits most days for some time. Withdrawal from this can be sickening and dangerous. I recommend planning with and monitoring by a medical professional to keep you safe during this period.
For now, be kind to yourself. Plenty of us have experienced these sorts of challenges on our sober journey. You are making the best decision for a new and better life. You’ve got this!
