Some people have the side effects that you describe and others do not. My experience has been that they do wear off if you do not discontinue and then start again, but unfortunately for me, I have developed a tolerance for Lyrica and the analgesic effects have diminishd even at 1500 mgs during the day and 750 mgs at night. (No physician will prescribe this dose, so I endure periods of agony when I run out until my next refill.) Physicians do NOT realise the scope of my pain. I have begun to consider suicide as an option.
