Been on So many Meds, including Dilantime, Mysoline, Phenibartial, Zoloft, Depakote, Tegretol which I take now, and Gabapentin, which is the Generic brand for Neurontin. I can write a book with all the meds that I've been on. But yes I get Tremors All the time even now as I am typing this answer!

Regarding not able to afford your meds, contact the manufacturer and they will help with cost. If you do not have insurance then they will be able to send you some medication. Also ask your doctor to write to your insurance company and see what he can do. The doctor can challenge your insurance company for a medication . Otherwise contact the manufacturer of the medication and they will usually help. I'm not sure who manufactures Dilantin but you can look it up on Google.

You should try to look into some type of ins so you can afford them- not good to be on one day and off the next. ( medicaid, medicare, united healthcare, etc)
