Hey,
I used propecia for about 8 years and for me the worst side effects for me are the cognitive ones.
I also have problems with my memory, speech, anxiety, lack of motivation, concentration.
I have now been of the drug for about 3 months and I am seeing a slow improvement. The cognitive sides are improving for sure, but I am still not back to where I was before propecia.
It seems to be the trend for most guys on this forum that the cognitive sides get better within 3-16 months, it just depends on your body. I am definitely seeing an improvement, so I am glad, but it is a slow one and will take a few more months for sure.
I did have a crash after I stopped taking the stuff. For the first 4-6 weeks I felt great and then I hit a huge wall and crashed badly. All the symptoms came back strong and I felt horrible. This lasted for about 1 week and things started to slowly improve again. It is probably our hormones and bodies just re-balancing, so it will take some time to get things back to normal.
I also had times where I had a bad headache and it felt like a clamp was on my head, it would come and go, but since the last crash it has not returned.
Give it some time and the cognitive sides should improve and resolve slowly.
Gino
