Frank, I just doubt that LDN is having that lathargic effect on you..

Could it be one of your other Meds and maybe LDN is not mixing well with it?
LDN usually has the opposit effect, as it causes you to be up, because of the raise in endorphins...it may even cause insomnia at first.
I sure hope you can get this worked out. I want you to benefit from the 3mg LDN, as I don't think the lower doseage does much.
Good Luck.
