My son experiences extreme heat every time he gets to lie down for a rest. The only thing which helps bring the heat down is to get up and walk. Sitting has got to be in an upright position. He feels very miserable unable to lie down as he's thoroughly flat out. He's been on 0.5mg klonopin for the last 2 years. Is it time to up the dose or is this neurological? Will beta blocker help?
