"i was quite sore from excessive coughing from an up and down bout with the flu. took one tylenol 3 tab as prescribed and was actually able to sit up and move around in bed with no pain. however, it did make me slightly dizzy with mild stomach upset. i would not take it when i have to be up and about. took it at night anyway so i could rest. i can live with the side effects since it&#039;s nighttime and i&#039;m in bed anyway."
