I certainly could see that there are a lot more Tirz users - in this case I've seen a few testimonials from mast cell patients who switched from Reta. I do think that the Glucagon activation's impact on heart rate is a negative for most of us that already have Dysautonomia or POTS of some type. I also have ADHD, so the anhedonia side-effect may be another part of the balancing act.
I was already having side effects at 2 mg Reta to where I tapered back, and I escalated rather slowly over time. The oddity is I had definitely impacts on appetite even from low doses, but suspected maybe inflammation was holding the weight from dropping. I wanted to see if I could reach 2.5 mg, but it wasn't to be. I dropped for a few weeks to 1.5 mg, and then to 1 mg. I felt better as I went along, both mood and other sensory issues seemed to fade out.
So, yesterday I had my first dose of Tirz at 1 mg. I definitely felt something different, and so far I am going to say that I can understand what people were talking about. My respiratory function seems a bit less labored. My pain level is better, despite not getting to sleep until 4 AM, and I had two new lots of IVIg today for my infusion and I had almost no side effects, which is rather unusual.
My food noise is about the same, but it has been only a day, and I probably am still spinning down from the 1.5 mg doses of the past. Food tolerance is still fine, and if anything GI system is more quiet. Time will tell how this experiment goes - I wanted to see the difference before I suggested one way or another to other friends in the chronic illness group.
