I started in November 2022. I also experienced severe jaw pain for about 20 minutes with my first 2 doses. After that I no longer had jaw pain but I continued to get severe headaches. I also developed tinnitus. After a month I was ready to stop the treatment but I found this group and learned that the dosage could be lowered. My doctor was fine with that so I tried stepping it down. I was still having side effects so I decided to take a week off (lots of family visiting over Christmas). I then started back at only .3. I’ve tried upping it several times but just dont feel well. My specialist is fine with this. My body seems to have adjusted now and I’m not having much side effects any more at .3 so tomorrow I was going to up it to .4.
