After I "crashed" from the Prozac, I had about 8 months of a med nightmare. I saw different doctors/psychiatrists in an attempt to get my anxiety back to normal. I reinstated Paxil in November of last year along with some other meds that were helping me sleep from all the drug changes/issues. Since January of this year, I've weaned off all the drugs except for Paxil. I now experience good days and bad days since dropping all the other meds. I've lowered my Paxil from 30mg to 25mg to 20mg. I did those drops over 6 weeks time. My understanding now is those reductions were too big. I shouldn't be dropping my Paxil down more than 10% per drop. At about 14-15 days after each drop, my anxiety increased a fair amount and this lasted for about 7 days until it eased up again. When I dropped to 20mg, the same thing happened. At 14 days, my anxiety really elevated (stronger this time) and has lasted now for 8 days although yesterday it felt like it eased up some. My goal is to quit this drug and stay off all of them. At one point I was on multiple anti-anxiety drugs. It didn't help and I was still for the most part anxious and had a TON of breakthrough anxiety. After dumping all of them accept the Paxil, again, I have been greatful to have days again where I feel almost normal.
It appears that anywhere from 20 to 40% of people who use SSRI's have some really strong withdrawal or discontinuation symptoms. Some people struggle to quit these drugs, if at all. The sad part is, most doctors and psychiatrist don't share the potential horror of stopping these drugs that they are so quick to write prescriptions for.
Anyway, my goal is to do a 10% taper (and waiting between 3-6 weeks between each drop) off the rest of the Paxil. As for you increasing your dosage, I did up till 30mg. I didn't see any measurable difference as I increased the dosage. What did happen is the side effects of this drug increased significantly.
