Health above everything peep! Stable is what you need!
I'm on keppra for epilepsy, and yes it did make me gain 20 extra pounds (bringing me to an unpleasant 235lbs. Normally I was 215lbs and losing weight.), BUT it helped! I have to take it for the rest of my life which sux, but if it helps you, it helps you.
But do not forget to weigh the pros and cons!!! For me:
Pros:helps reduce seizures, suppressed appetite
Cons: weight gain, suicidal thoughts, depression.
Everything has a side effect. It is up to you what you can handle. Hope that helps.
Have a good day/night 🙂
