At bedtime last night I took my medicine as I always do. I went to lay down in bed, but this overwhelming bitterness started to hit me, and it was making me gag. I tried to swish with water to knock any stuck pills loose from my mouth, but it had no effect. I gagged more. Finally, I grabbed a Tums to chew on and hopefully knock something loose, which it did. The bitterness remained about another 30 minutes, and the adrenaline from it all for a couple hours. I didn't fall asleep until sometime well after 1am.
