Compulsive behavior x self control

I have observed that my ability to control emotions, behavior and desires in order to obtain a reward has decreased drastically since i took propecia. I used to have a lot of self control, i could abstain easily from a lot of stuff. On the periods of recovery i had, this was reversed, and i felt like me again. On the other hand, on the periods of crash, this became worse, reaching a point of compulsive behavior (specially with masturbation and some foods). To me it is clear the lack of neurotransmitters or whatever substances and hormones are missing has affected somehow the brain’s reward area. Right now it is ok, somewhere in the middle, not as hard as on a crisis and not as comfortable as my old self. What i want to know is… Do you guys feel this way too? And if yes, what do you do to improve self control?

during the crash and even now. i feel like i am control…TOO in control, i was a wild person, now i am much more guarded and picky , i dont know if thats a good thing or a bad thing, however i used to have hunger for food and now its just a little desire for it.

I certainly have noticed an increase in compulsive behaviour, along with difficulites in concentration and self-discipline generally re: getting work done, meeting deadlines etc. I have no doubt that this is linked to neurotransmission problems. I am trying to develop strategies to tackle this e.g meditation etc but it is seriously hard going.
On a similar and possibly related note I seem to be having diffiuclties with dehydration as my brain does not seem to be receiving signals that liquid intake is required i.e. I rarely feel thirsty even when going hours on end in a hot climate without taking any fluids. I have to remind myself to drink water on a regular basis.

Exactly what i mean.
