When I used products with pseudoephedrine, I felt it can be addictive, for it helped clear my sinuses but also gave me a "lift", even dulled appetite, which was good for being on a diet. I noticed there was some relation to possible addiction, when not using it, I wouldn't feel that little energy lift and normal hungry appetite returned. Which I couldn't wait to safely take the next dosage (every 4 to 6 hours) seeming like a sign or warning a form of an addiction was forming. I feel if one has cravings and then goes onto strong cravings for something that is a sign of possible addiction, but just my own opinion, of course. Eventually I couldn't use it, first they discontinued that ingrediant and used a substitute that didn't work, and with my weight gain/thyroid problems it did something it never did to me but can do to people, raised my blood pressure.
Pseudoephedrine, has been taken off the market because of it's use as an ingrediant for making methamphetimines/illegal drugs.

It's ashame when some have to ruin it for others, cause the OTC stuff with it was very effecient in helping me over the years with congested sinuses.
If it is still being sold where you live, I'd personally try to not use it, I also found depression creeped in, sort of like coming off amphetamines, not helpful to Bipolars.
