Congrats on 5 days! That is really awesome! You will be feeling better in no time. Its totally normal to not get much sleep. Been there..still there! Hang in there! It gets better!!
Five days! Good for you. I just posted about my own sleep problems, but I want to encourage you to hang in there. Even though I'm still not sleeping well, the anxiety is gone. I no longer feel anxious at night or feel the startling sensation you describe. That will pass and, even if you don't sleep, you will at least be resting and relaxing a little better. Hang in there! It gets better each day!

Congratulations on day 5. What you are experiencing is normal. You can certainly us the gravol as that will help with the phlem as well as sleep. It takes a while for sleep patterns to return to normal but don't give up. There are a number of solutions out there but without knowing more about your case it is hard to point you in the right direction. Hang in there....the roughest is almost over!
