I've been using this for several months and it works well for me. I am bed ridden so don't really burn off energy, boredom yes, but I find these work well for me. I take them 15 minutes apart then my nightly meds about 15 20minutes later, nightly prayers and then I take a gabapentin along with one all purpose allergy and sleep sound. Before I began this regiment I was laying awake all night for I have much pain. But I look forward to bedtime now knowing I won't be staring at a dark ceiling all night and will actually sleep sound. In my life sleep is extremely important because my pain levels are there not long after I take my pain meds and pain robs one of the good things in life. So After finding and buying Physicians choice I've found all natural no chemicals or fillers, What I purchase on auto fill every month all work to my benefit, I highly recommend this company for your needs.
