Hello. i sweat profusely most times of the day, but at night I often wake up soaking wet. i also have noticed a pungent Vinegar type smell on the pillow, and often on my hair, especially behind the ears. i shower everyday, change shampoo and gel brands fairly regularilly but this seems to have no effect. i am overwiegt, by around 50-60 lbs, and i am male 42 yrs old. the vinegar smell has happened in the last few months, but the sweating day and esp at night has always been a problem( even when i was a good body weight) i never use a cover and sleep in only boxers. advice please?
