Helped me to not eat so much at meals. Thank youI only eat once a day. (Fasting) I've always been this way since about a year ago. It's what keeps my weight stable I DO TAKE IN MY DAILY NUTRITIONAL NEEDS DO NOT STARVE YOURSELF PLEASEEEE. Some people cant handle fasting and get very nauseous. I gave this 3 stars for comfort because of the side effects. You CAN prevent them if your not sensitive to niacin and if your perspective to your habits. This is only my second day taking it. I take 2 a day due to the fact I only eat once a day. And you take 2 with a full glass of water 15 minutes before you eat. I will warn. First day, took first dose around 1 and went for a mile run. I had a headache for the WHOLE day up until I went to sleep. It was a little hard to sleep but I am diagnosed with insomnia also so this may not pertain to others or even yourself when it comes to side effects. I did get a singular stomach pain after I ate (oops i ate a lot of carbs) try to stay away from a lot of carbs when you eat, or it will raise your blood sugar and you will become almost jittery. Stay away from other caffeine. I only drink water. Second day (today) taken at 12 with a full glass of water (16.9 fl oz) approximately 1 water bottle. And once again went for a mile run. I did get hives/rash but only when I ran. No itching, or burning. I just became a little red due to the fact that my body was trying to quickly use the energy the supplement is giving me when I ran. If you itch or burn and its doesnt go away STOP TAKING IT you are having negative reactions to the niacin that may effect your health deeper then just the side affects. Mine Went away within 10 minutes after I stopped running. DRINK A LOT OF WATER. BE MINDFUL OF CLENCHING YOUR JAW(both associated with a headache due to niacin and massive amounts of energy) today I have not gotten a headache. I realized I was clenching my jaw too much yesterday so I stopped. I also drank more water today. I started out at 155. Usually the first 10lbs are water weight but I am down to 150 in 2 days and I'm very excited to lose more with the weeks to come. This bottle will last me 2 months (bc I dont eat more then once a day) take a 2 week break after 1 month of supplements or your body will get used to the key ingredients used to lose weight. If you've ever taken melatonin to sleep you know what I'm taking about when I say your body gets used to a supplement after a good bit of time. I hope this helps anyone who has questions. I might update this after my first month to let all of you know how it's going :) be mindful of your beautiful body and dont force yourself, dont push too hard. It takes time ❤Great boost of Energy!!It works for me without side effects.It’s a good product for those who are starting off their weight loss journey.Works great.This actually gets me up and going in the morning and am not usually hungry til 3:00 PM. Been on it awhile beats getting it at the storeThis product really does work well for me. I know everybody’s body is different but it really does keep the hunger control situated.
