Clearly placebo for me, I guess? It's wild how many people are saying phenylephrine is completely ineffective. It saved my ass during a really long COVID stint. It was impossible to find by itself but when we finally found it we bought 2 boxes because we use it and, for us, it works wonders... Hope they release something else better I guess.
The better thing is the original: psuedoephedrine. It was never impossible to buy, it just required going to the pharmacy counter and showing ID. I knew about this when it happened in the 2000's because my dad needed Sudafed often, but the changeover was almost certainly invisible to most people given that the packaging is essentially identical between the two versions of the product.
