I became a vegan about two and a half weeks ago, and regularly work out lifting weights, and run for an hour, three times a week. I've noticed over the past few days that my body absolutely aches. I've taken a few days off running because every step I take feels like I've just ran a marathon. I'm only 21, and have quite a high pain tolerance, but I've had to stop twenty minutes into a jog and hobble away in agony. Previous to going vegan I act a very clean, healthy lifestyle so I didn't notice any detox signs, and I've done many cleanses throughout my life and nothing has ever came close to this. Has anyone ever experienced this before? I'm wondering if it's something I'm lacking in my diet? I've tried increasing protein, and am taking my vitamins daily, but this is getting a bit absurd. Especially when I feel the need to stretch out my calves every five minutes because they feel as though they're about to fall off. Please help!!
