My husband has been on lyrica for about 6 months. It was helping the burning pain and tingling for neuropathy but isn't working anymore so they want to up his dose. He has become paranaoid, thinking I am out to control him, he has become violently angry , losing hair, dangerous weight gain, swelling, fluid retention.....the worst part is that the effect on his brain makes him in denial that it is the drug so he is increasing it. I am considering leaving before he hurts me. Be careful- it is a dangerous drug for some people.
