If you still have at least a few days to a week left I would recommend meeting your doctor and asking about sleeping meds. I'm a big time insomniac and short of following a rigidly planned out schedule or walking for
hours to tire myself out, that's whats helps me when it gets too bad to function. Inform your doctor of any other medication you're on, anything you've been on that you've reacted to, any dependencies to medications before etc.
I'd recommend taking the first dose a few hours before you intend to sleep because it usually takes a while to kick in. Do not sleep with an alarm, sleep as long as the tablet lets you as it's essentially forcing your body to readjust to rest mode. During the day, do not operate heavy machinery (no driving...or street crossing either actually lol) or make any major decisions (tests, work etc) because you will be under the influence of whatever drug you've been prescribed. Stay home if possible, and let your body rest.
Depending on the person, some people start to feel more comfortable during the day and start feeling sleepy at night/late evening on their own and can wean off it within days. Personally, it takes 2-5 days depending on how sleep-deprived and exhausted I am, but I clear my schedule for that week just in case. Once I start feeling sleepy in the evenings and going to sleep normally, waking up feeling rested in the morning etc, I immediately stop cold turkey and (in extreme sleep-deprived cases I gradually lower the dosage until I stop) then the real work begins.
These are the methods I use when I'm not as badly off, but even with meds, I return to this to keep myself on track:
- Drink lots of water throughout the day. Avoid dark beverages, caffeine, and alcohol. Aim for a guideline of 6-8 glasses a day. [*Surprising fact: Not everyone's hydration requirements are the same]
- Eat well. Opt for fruits, vegetables, freshly prepared meals etc whenever you are able to. Unhealthy, highly processed, artificial foods etc really do mess with your system and can make you feel unnaturally bogged down or alert at inopportune times.
- Be active during the day. I've found this includes mentally as well as physically. Stretch, even for just 10 seconds in the morning, to prepare yourself for the day ahead and wake your body up. Then get to work. Staying seated for extensive periods of time does take its toll. Stretch your legs at least every hour or two, more often if possible. Do something to stimulate your brain during the day. Read, play brain building games, learn something new etc.
- Start winding down at least a few hours before you plan to go to sleep. No caffeine, avoid bright blaring lights (TV, PC etc) and focus on relaxing activities immediately before bed.
- If you can't sleep, get up and do something for 20 minutes. If that doesn't work, try something else for 20 minutes. Lie down and try again. Rinse and repeat.
- Try meditation. Or try one or two simple relaxing yoga poses. Find something that works for you that helps you unwind at the end of the day. Check out this thread for stress relief and pick-me-ups.
- Consistency really does make a difference. When you find something that works, try to keep at it. Make note of what works so if you do go off track again, you'll know what worked the first time and can try again without all the guesswork involved.
Good luck!
