"It took me a couple of weeks to adjust to the vitamins and find out what worked for me. When taking the recommended doses (3 AM and 3 PM) I found that it was a little too much for me, and this is coming from someone who has been taking a good multivitamin daily for years. These are pretty harsh on my stomach and I can really only comfortably tolerate them when take just before or after a meal, especially the PM vitamins. I cut down to 2 AM and 2 PM per day, each taken with a meal, and found that I have noticeably better energy through the day. I found that taking the PM too late or right before bed can actually cause me to to toss and turn all night, so I started taking it around 5-6 pm with dinner. It took a little while for my body to get used to to the PM vitamins, as I felt like I still had energy to spare when going to bed, but now I sleep like a baby. All in all I think these are pretty good quality vitamins, and they’ve given me noticeably more energy through the day. It just takes some experimenting to see what works for you as far as doses go. There is a period where your body will need to adjust and build a tolerance to the extra energy, so you may feel a bit jittery or wired for the first week or so, but it evens out soon after, leaving you with a good amount of energy through the day and restful sleep at night. There are other reviews complaining that this supplement makes it hard to sleep at night, and that may be true for the first week or two depending on your tolerance, but I assure you that effect wears off. It’s just your body adjusting to the energy that you get from the AM supplements."

"These elitist little capsules do deliver on their name in both price and quality. They are expensive, but I have noticed much more steady increased energy, a general feeling of well-being, and therefore I have an everyday desire to take them. The night pack have kept me up and stirring before - maybe too much juice for my needs - so I've taken one of them evening every other night or so."
