I have a 2-week-old and we've had some breastfeeding challenges. I think the solution to some of our issues is to increase my supply, so I have started taking More Milk Special Blend (the alcohol-based tincture). Is this something that I will need to take long-term once I've started? Like, if I take it for a few weeks and then stop, will my milk really dry up, or is it something that I can just use short-term as sort of a jump start? It's so expensive that I'm scared I won't be able to go off it!
