I am reducing my intake if Gabapentin and replacing it with Lyrica, but my feet have gone from intense burning to intense chilling, they are so swollen and sensitive I don't know where to put them. Yesterday I reduced 900mg of Gabapentin and replaced this with 200mg Lyrica( I have been tapering since Friday) I also can't sleep, it is 3 am and although I am intensly tired I cannot sleep for the pain. Should I just give up the notion of Lyrica? Any advice will be greatly acceptable. Work tomorrow morning is looming and I don't know how I will get through the day
