Well done for spotting what was happening and following your plan through by contacting yiur sponsor and letting him help you climb out of the vortex.
Never mind that can. Just that sip was enough to topple you into the dangerous waters. That numb feeling sounds to me like your AV was in the drivers seat. And I remember that feeling. Almost like being a bit drunk before I'd even had the first drink of the evening. Like being a the top of a roller coaster in free fall.
Scary stuff. So glad you're still with us. Stay close.
