In my opinion, remember that whenever you switch meds, , start, stop, adjust dosage it can cause some temporary
side effects while your body adjusts, but if you are doing it under the consultation of your doctor then you are doing the right thing.
Now, as far as buying meds off the internent and experiementing on your own; in my opinion that can REALLY get you into trouble. As soon as you go and work with substances that are not regulated I don't think any good can come of it.
