If your doctor prescribes a medical sleep study, don’t be afraid that you (or your husband) won’t be able to sleep in a strange place; a mild sedative will help you ignore the wires.  Those who’ve done it and been prescribed the CPAP machine for apnea have found the tremendous increase in energy from a good night’s sleep worth the bulky machine.  Most lose weight because they just feel better in every way, breaking the vicious cycle of overeating because they feel tired all the time.  Often when the weight is lost, the machine is no longer needed for a night’s sleep.  Good synergy.
