Your only current post on Lemmy is this one asking for places you can by a med that just so happens to contain pseudoephedrine. I'm not saying you are buying it to make drugs but that is a really bad look regardless.
If you are genuinely just somebody looking for an alergy med then you should really look for a different one. Pseudoephedrine is not good for long term use and there are far better alergy meds available. If for some reason that is the only drug that works for you then you should get a prescription from your doctor because even though it is an over the counter drug, a lot of places have stopped stocking it over the counter because it is used to make meth.
