Can you tell me which is the best product for me? I am 47 yrs old, a nurse, I work night shift and so my sleep is horrible and I'm storing fat around my abdomen in the last few years. I do have hypothyroidism also. I have taken meds for it since 18yrs old so it is nothing new. However, even though my levels are normal, I feel tired all of the time and I have no energy to workout anymore.
