Mind Control

Posted by 5215232595146304186 on Jan 05, 2017

I originally started taking this supplement in the morning with my coffee and my prescribed Wellbutrin on a empty stomach and I honestly could not feel anything different. But I started to experiment and I found that if I took it in the late afternoon it helped eliminate my binge eating in the evening. Of course the only foods I wanted to binge on were sweet and salty. So when I would start to feel like I wanted to eat, I would stop and ask myself if I was really hungry. When I started taking the 5-HTP I found it easier to listen to my body's response. I actually felt like it helped my body feel more satisfied and I had improved will-power to overcome the urge. It also did not interfere with my sleep which was important to me.
