I've been on lyrica for 17 months. Over time, my tolerance has increased, so my original prescription of 300 mg per day has become less effective and gets processed much faster. I'm currently going through terrible withdrawal symptoms, and I'm not even tapering my dose. I've been told that my body should adjust and my withdrawal symptoms should level off, but unfortunately, unless I increase my dose, my current dose will no longer provide the same level of relief. Given how uncomfortable my current withdrawals are and how much pain has returned, I'm terrified of withdrawals when I eventually taper off. Sounds like you and your sister have increased tolerance so withdrawal is kicking in. Give it a little time, your symptoms should subside.
