Hi Daisy,
I would check them out with Skip too. I weaned off of Neurontin to go on LDN. I was up to 3600 mg of Neurontin and it stopped helping me. I took Neurontin for 5 to 6 years. I had to wean off very, very slowly. It is for sensory symptoms, and is sleep inducing for some.
It is really for Epilepsy but used off-label for MS.
Some people take small doses. What dose are you starting on? It is addictive, believe me. Your body craves it after a while. Some people can't take it at all.
If you decide to take all three. Please space them. JMO
