I have been lifting weights fairly consistently for the last 17 years, but did not work out for about 11/2 yrs., and got back into it about 6 months ago. Since 9/29/13, I have lost 48lbs., and stopped smoking for almost 5 whole months!!! (12/10/13). But before July, none of this would have been possible!! In July, 2013, I finally found out that I have Narcolepsy, now I am taking this powerful medicine and wake up, to feel like I actually slept!!! Before that I felt like I had just taken a bunch of sleeping pills! SUPER TIRED ALL THE TIME AND NO ENERGY!! But this medicine gives me 1,000mg. sodium, so I have to keep my sodium down to 1,400 or below!! And probably for the rest of my life! Plus I have to go to bed at pretty much the same time every night and wake up at 2 am. to take a second dose every night. But now things are much better!!!!!!!!!!!
