Hey Tambo,
Me too! I had a huge spike in my 5th week, followed by two weeks of almost half the units in that spike. Then another spike, followed by even lower units the next few weeks and so on. On my doctor's advice, I increased my dosage to 75mg in the 5th week. I increased to 100mg in the 17th week.
I can't say if the dosage changed anything, I might very well be in the same place if I was at 50mg the whole time. But I can say my overall trend is down, slowly but surely. And I continue to have spikes along the way. I take comfort that the spikes are always followed by lower numbers in the following weeks.
I know you know this, but it is worth repeating. You are only at the beginning ... 5 weeks is not very far in when you consider that this could take 3-12 months by accounts on this forum. Please try not to overanalyze and get discouraged. Just stay the course and things will happen over time.
Hugs
