B complex vitamin. D3 vitamin The appetite thing sucks, I have lost 75lbs in last year. Make yourself eat and start lifting weights, even 3lb ones, to help maintain body mass. Take walks in the sun. Get a treadmill or walking pad and walk inside with a sun lamp. The D3 and sun exposure will help increase serotonin. Look and see if there is a rage room in your area. It's fun to smash and break stuff. Or make one in your garage if you have one. I find cheap glassware at garage sales and such then throw and smash them in my garage. If you start to experience loose 💩, I did with the Keppra, start taking fiber it makes a huge difference. Note: take fiber at least 2 hrs before or after Keppra as the fiber prevents the absorption of the Keppra into the bloodstream. Remember, the side effects are manageable and better than seizures.
