...ah...BTDT, about 10 years ago I was given an oral med for a severe case of Athletes Foot. Griseofulvin, a few days later after several visits back to the Medical office (oh you're catching a cold, or its the flu going around), I went into anaphalactic shock...flat-lined in ICU. One week in a private room and sympathic cute RNs.
Two weeks later the ER doctor tells me "Bob if you would have come in 30 mins later, I wouldnt have been able to save ya..." I truly didnt know what was happening at the time. My ex GF drove me the hospital otherwise I would have just stayed in bed...(permanently)...things didnt work out between her and I, but if it wasnt for her...
