Sudafed/Benadryl, it seems that Benadryl is vastly more flexible and preferred as the EDC of choice by many, in spite of the drowsiness (which as some have mentioned can be a feature)
Benadryl has another benefit in that it reduces itching, and while the drowsy effects are not always wanted, it’s a good trade if it reduces itching that’s driving you up a wall.
As I've said here a bunch of times, I have a chronic wound condition, and I regularly get the "itchies" - my MD said "drop a benydril"
RE Sudafed - love the way it works, can't take them anymore, HBP will do that to you
