reverse osmosis

I haven't been on here in quite awhile. Probably 3 yrs. Due to my declining health. I bought a house 3 yrs ago.. And a salesman came about a whole house water filtration system.. when I moved here I was FULL of life. I had more energy than a 16 yr old, I was 34 at the time. did all the cleanses and drank my superfood daily from dr schulze...So I had this put into my house and I was sold on not buying spring water anymore at the store... And under the sink they put one of those reverse osmosis water filtration systems in .. and I started drinking it all the time instead of bottled water.. I started to get really sick.. 2 months later.. Unable to get out of bed most of the time to run errands or even work from home .. I would fall asleep every 2 hours... I better now .. however I never feel good and spend every other month sick pretty much for the last 3 yrs... I have been drinking this reverse osmosis water.. and no matter how much i drink I am THIRSTY...NOT even my superfood and yes i take b12 shots even though u don't recommend them.. truly is helping me at all.. So today I am thinking is it this reverse osmosis water? that is making me so sick and a constant state of sickness? I never know how i will feel from day to day...And all that i know I have learned from here probably over the last 8 yrs and I cant figure this one out now. I am now 37 and feel like 87.
I do know that I need to a whole round of cleansing. And start over I guess...I just want my health back.. I was so energetic and on top of the world.. and now i feel dead.
