I am just getting over a cold/allergies. After a few days of coughing and sneezing, stuffy nose = not ebing able to sleep for more than and hour or so at a time, I was flat out exhausted and had to bang in sick to work on Friday. I am a firm believer that rest does a body good.
That said, I tried for the second time, Tylenol sore throat and cough liquid (Night-time). It's a bluish color and be prepared if you take it. within the hour you will be out like a light! It's weird because you never feel yourself getting tired. You feel your throat feels great, no coughing and then bam.....out cold! I woke up on Saturday after a solid 7-8hrs of sleep feeling like a new man. Last time I used it was last year or the year before. Worked like a charm then too!
I am like you as well in that I tend to hold onto cold for a looooooooooooooooong time. When I get the flu it's usually a day of feeling ehhhhh, 1 day of "I wanna die", and the next day is a "I wanna die/maybe I can eat something now" day. After that bad day or so I recover quickly. I know some people have the flue for a week plus, but I tend to get rid of that quicker. It's colds that stay with me like ......well a cold I guess.
