Getting off medication?

I have been feeling okay lately, the past month or so I haven't noticed any pain unless walking a lot or sitting for a long period of time. I'm currently on 50mg lyrica that I take at night. I tried just one pill yesterday so 25mg and I really felt it today. Pretty much limping by the end of my shift, and lots of tingling. I'm not sure if this is how the first couple days will feel or if I'm just going to be on medication forever. Has anyone else tried. Getting off of medication? It makes me forgetful and depressed, but even then that's better than pain.
