That's what I thought? I think doctors are worried about being libel about being sued if their patience get addicted? Their Really coming after doctors?
Doctors these days give small amounts of pills in their prescriptions specifically for that reason, but they don't refuse to give the patient anything when they have a sleep issue.
There are other things you can do also to improve your sleep. Take a magnesium citrate supplement to relax your muscles, ask your doctor if that's okay since you are on prescription meds.
Get some exercise every day, even a one hour walk or two half hour walks at a good pace will get your heart rate up and make you more tired at night.
Eat your last meal earlier in day, if you eat supper at 6 or 7pm, switch it to 4 or 5pm. That gives you a longer time to digest your food before bed, so your system isn't doing that when you're lying down getting ready to sleep.
What time do you go to bed Pat? If you usually go to bed at 11pm, make sure you turn off your computer an hour before, and it's best not to watch TV either right before bed if you have trouble with insomnia.
There are teas at the store like Celestial Seasonings Sleepy Time tea, you can try a product like that. It's not too strong and it does help people. Don't eat any snacks for a couple of hours before bed, basically try to start to unwind and relax long before bedtime. If you really want your sleep to improve and you're willing to make some simple changes, you'll succeed. Good luck!
