You'll probably want to look at this recent thread:
Mitigating sleep issues on trenbolone
In addition to the previously mentiioned PM thread ("A Solution to Tren...."),
@Type-IIx has a post on Androgens and GERD, acid reflux, and peptic ulcer [by Type-IIx] (
Androgens and GERD, acid reflux, and peptic ulcer [by Type-IIx])
The scope of that article does not include Trensomnia, but it's still great background.
Managing the mast cells
For sleep and respiratory issues, want compounds that target the H1 receptor. (like Zyrtec, and Benadryl, though everything has side effects see the warnings about diphenhydramine/Benadryl)
For GI issues, want compounds that target the H2 receptor. (like famotidine, stinging nettle, holy basil, quercetin)
The wikipedia page for Mast cell stabilizer lists, among others: ketotifen, vitamin D, quercetin, and beta2-adrenergic agnonists (like clenbuterol, salbutamol/albuterol)
Note that I make no claims about the accuracy of these posts. I'm just summarizing them. However, if Type-IIx has written something on a topic, I generally take it to be a reliable starting point.
