My neuros have told me I can take my 300mg either 2-3 times a day depending on how I feel in the afternoon. We’ve tried to wean off but it didn’t work as I’ve taken it 9 years for seizures, multiple headache types and neuropathy pain. As long as your doctor says you can adjust it it’s ok. You just can’t jump off immediately as it’ll cause symptoms. It’s not addictive and can work with a other meds so that’s why it’s readily prescribed
