Hey - good to hear from you again - and apologies for the late reply. Been stupidly busy.
I remember your story well, and whilst good to hear that your withdrawal had been going well, it is unfortunate that you have done a u-turn. If the Effexor was working, it may be wise to go up a little before throwing it in for another drug, which may or may not be the right way - as Hat said, it is the flip of a coin.
If you have had difficult circumstances, then what you are feeling is obviously par for the course - the question is whether you feel this will pass in time, of whether it has pushed you too far. Never a good thing when something like this happens during a withdrawal. We get so fragile at these times and need to be so careful - but sometimes things are inevitable and beyond our control.
The 5HTP might work and is a possible, but much like an AD, works for some, does nothing for another. No one brain works the same way. No one drug works the same way. I mean they all state that they prevent the reuptake of serotonin, so logically that would be one process - so why do we have a dozen different pills stating they all do the same thing?
I'd tread carefully the with 5HTP - it will show itself to be working fairly quick if it will - and make sure you get a very good brand as there is so much rubbish out there which uses the worst possible ingredients.
Keep us posted!!
