no what i meant is can i take 2 tablets at once instead of seperating it by taking one twice a day. second question. today i was blood tested again and the name of the test on the sheet said "small fiber painful axonal neuropathy". i had no idea there is a blood test for small fiber neuropathy. is this a bogus test or can this test really give me some answers? i was told the only way to find small fiber neuropathy is via skin biopsy.
