What you say makes sense, I guess in liquid form it is diluted and dispersed throughout the liquid. I'm sorry for any inaccuracies, I never touch that stuff. I even have a cold right now and won't touch it. I stick to Vick's!
I'm sorry, I wasn't trying to be snickety correcting you about the stuff. The only reason I knew about the pseudoephedrine is because I was talking to our undersheriff about cold medicines one time. We both weren't feeling very good so we were talking about over the counter medicines that worked for us. He was talking about how well Nyquil worked for him and I was telling him I couldn't take Nyquil because the pseudoephedrine would make me feel like I was about to jump out of my skin. One thing led to another and we started talking about the meth problem we had in our small town. Of course this was before our local state trooper was killed by a local firefighter because the trooper rolled up on the firefighter in his mobile meth lab. The meth heads were making the stuff in their cars because there's a really strong smell when meth is being cooked.
When Nyquil quit putting the pseudoenephedrine in their formula, the undersheriff called and let me know. Now I can take it because it works better than benadryl for me and it doesn't have the side effect it used to have. If you can tolerate benadryl, you probably would be able to use Nyquil now.
