Hi Hazzel, welcome to NeuroTalk and to LDN.
I started on 3mg in April of 2003 and went up to 4.5 a couple of yrs? later. I didn't notice any difference, but I was already on an optimal dose.
You are on a pretty low dose, lower than is recommended, so you may notice LDN working better at 3mg.
Good luck and please stick around to enjoy our forum and to keep us posted..
