Hey guys, so 2 years ago I had some troubles getting a restful sleep (still sleeping deeply, but not feeling rested in the morning) so I purchased 90 caps ZMA (Optimum Nutrition). It helped me a lot from day 1 and I was able to get back in tracks after a month of using it.
Lately, I've been having the same problems so I again bought ZMA, same ON product, same formula and ingredients as before. For the first 10 days, I was also following the same routine as the first time - 3 caps 30 min before bed on an empty stomach (I never had luck with eating before going to sleep anyway). This time, though, it didn't work at all.
So I read some advise to work your way up, taking 1 cap in the afternoon going later and later each day (again on clean stomach). So this is what I did for the next 2 weeks - 1 cap in the first 7 days, 2 caps in the following 7, gradually going from 1pm to 10pm. But yet once more this brought no results. For the last week, I got separately some zinc and magnesium citrate from a colleague - taking the zinc (40mg) in the morning and the magnesium (600mg) 30 min before bed, not eating any milk products for breakfast or last meal. Again - nothing.
So what could have caused this change - from a supplement, that was working like a charm from day one for me few years back, to a sugar pill now. Few thing for the record - I didn't feel any stomach discomfort and/or energy boost while taking ZMA before, and I don't feel any now. I take B-complex every morning (B6 included), but no other vitamin or mineral supplements. Also, I didn't get any vivid/lucid dreams in the last month, which was surely the case the first time (I almost never remember my dreams, but with the vivid ZMA ones I did).
So any ideas as to what could it be? I actually got my Ca, Mg, Zn and Cu levels tested and they were absolutely normal. So I'm guessing malabsorption is unlikely, but I have no other explanation as to why I don't feel anything at all - be it positive or negative... because not much has changed in regard to my nutrition habits, working hours or activity levels from the last time...
