What can of meds are you on? Sometimes the medication you're taking whether it's over the counter or prescribed can change your body chemistry... I KNOW for a fact. I'm in the same boat you're in pjresses. Ever since I've been taking depakote my body has been reakin' like an onion or garlic. I bathe twice sometimes three times a day and I drench myself in perfume and BO smell good (aka all of deodorant). Plus... you can smell yourself better than others can. It's stronger to you than anyone else. I'm sorry I don't have an answer for you but I KNOW what you're going through and you have my sympathy and prayers.
