I felt a difference after only a week on this! After awhile I started to think it had stopped working so I went without for awhile, and I felt so awfully tired and groggy. I realised that I had just started to take the Enada's effects for granted, but going without for a little while helped me see the difference it was making. I hate having to wait 15min to eat breakfast with these pills though, so I have switched to the sublingual lozenges. If I crush them up a bit before putting them under my tongue they dissolve away in about 5min then I give it a couple extra min to be sure, that's only half the time it takes to let the pill digest. Those minutes are precious if you wake up ravenous like I do! Either form seems to work the same. I have had no side effects at all, despite having very fragile health. I mean, I can only handle one small cup of tea per day, stimulants just wreck me. But this neither revs me up excessively, nor leaves me with a crash after. It seems to provide a gentle, legitimate energy increase. Amazing stuff!
My mother had problems with chronic fatigue and every time she went to the doctor they said she was fine, all tests came back normal. She was also getting dizzy spells and having trouble remebering stuff. In the afternoons she would just be so tired she could barely keep her eyes open. I bought the Co-E1 NADH tablets for her and now she's energetic like a teenager again! She feels a hundred times better than before!
