Has anyone found that the natural supplement 5-HTP has helped with depression, pain and or constipation. Its supposed to help with sleep and anxiety too and have much less side effects than the SSRI's. I have read somewhere that it could cause constipation ... anyone had any experience with it.I'm IBS, very C type with lots of pain, gas, bloating and total exhaustion yet suffer from insomnia. Sound familiar to anyone? None of the pharmaceutical drugs help, so I was just wondering if anyone has had any luck with this product.
