Been on Nerontin for 2 weeks now. Burning in my feet are better at night but I feel fatigued and have stomach aches. Will it go away? Its great that I have relief at night from the burning sensation and Im able to get some much needed sleep. But Im am dragging my booty all day. I seem to perk up around 6-7pm. But that only leaves me a few hours to get some stuff done and then Im taking my meds at 10pm and getting ready to wind down for bed. I dont know, Im confussed.
