My husband just had his dose of Gababentin increased from 300mg to 600mg per day. He took his first dose on last Sat 7/8 and his second dose on 7/9 then stopped due to working with heavy equipment. On Tuesday 7/11 and now for 4 days has had night sweats, to where the bed is wet and need to be dried. Then today working in the garage about 80 degrees, came in soaking wet with sweat. Is this a side affect?
