I’m on metformin 1000mg two times daily to help with weight loss due to antipsychotics. We tried it for a couple months and I didn’t notice any weight loss so we finally successfully tapered down on the antipsychotic and up on an antiepileptic and wow! The weight is shedding off! The Dr is keeping me on the metformin until I reach my goal weight in case it is helping too. Best of luck to you!!
