I've signed up after reading about your problem. I have the solution for you. Take magnesium pills and the problem will be solved in days. Your problem isn't caused by lack of hygeine but lack of magnesium in the body and showering all day won't help.
Don't waste your money on expensive products and don't feel miserably anymore. All the symptons you've mentioned indicate magnesium deficiency in your body. Simply go the local drug store and buy magnesium supplements (they usually cost less than five bucks) and take the daily dosage, which is about 500mg, three times daily. Since you're probably severely depleted in mg you may double the daily dosage.
Health stores have different types of the vitamin. I recommend calcium-magnesium combination. Side affect is diahrrea and you'll notice results in probably after a week or two of taking the daily dose.
