With the capsule form of LDN - l believe you can only get 3mg or 4.5mg - so when starting on LDN it is recommended to start with a low dose and gradually build up. So l think you might need the liquid form first. lt tastes a bit like cough syrup - and the taste soon goes away with a drink of something.
lf your financing it yourself - then the liquid form is much cheaper. l have been taking it about 8yrs now. Time flies. For me it has made such a difference. l have PPMS - so no treatment on offer. And most of the meds prescribed for symptoms do not suit me.The side-effects worse then the symptoms they are supposed to help. Baclofen/Tizanidine - Gabapentin etc left me like a cabbage - and unable to get up and move around.
l take a high dose vitd3/b12/magnesium/probiotics/D-Phenylalanine omega 3/ mini aspirin/LDN/ and l also use Sativex. l do not get any brain fog/fatigue. l try to not eat carbs as they make me so tired.
l get my Sativex on prescription - but still pay for my LDN - although the neuro is all for it. l think if l pressed my GP~ l would likely get it on repeat prescription. l rarely go to the GP - and have not seen a neuro for a few years now.
