I work a lot of overnights, and due to horrible migraines, I've had to cut out caffeine, so I'm always looking for natural ways to boost energy. I got this as a sample in one of Birchbox's kits. The first packet I used, I mixed with less than 8 oz of almond milk and couldn't get it to dissolve properly, and I ended up throwing it out because it tasted horrible. The second time, I added the packet in thirds and used 10 oz of unsweetened almond milk. It helped, but it was still kinda gritty and wouldn't dissolve completely no matter how much I stirred. It doesn't taste great, but it tastes healthy and I did feel like I had more energy after only drinking about half. I probably wouldn't buy it because of the taste/texture, but it's definitely not the worst thing I've ever had. I'll probably still use the last of three of the sample packets.
