No hair loss that I've noticed, Mum.
Glad to hear you're sticking with it, the bump back up to pre-TSM levels is normal and your numbers should begin to fall off from here.
You can also try some mindfulness techniques, stretch out each drink, have water in between, don't keep the drink with you, that sort of thing. It helps break up the habit while the Nal is working away on breaking up the craving.
