Yesterday and this morning, I took 12-hr nondrownsy nasal decongestant pills, which were from Drug Mart, compared to the actual product, and last night, I noticed I was very sleepless, and on the back of the box says "stop use if you get nervous/sleepless/dizzy"... it's 120 mg so I think that's too much on my little body so i should go with 1/2.. should I.. I am only 95lbs, 4'11". or should I just stop that all together, because apparently, I only have taken two, and I am pretty restless right now, and it's only 8PM. It doesn't help me any better that I live alone now and I am quite a worry wart. Any suggestions/advice? Thanks.
