I like reta more because tirz gave me annoying constipation. Reta makes me feel somewhat cold though and I get a bit of allodynia on my arms. I can handle normal meals without feeling overly full and keep losing weight at a steady pace.
I shared a log and update in this thread, though I'm not yet at the highest dose of Reta. Noticed many switching over and was curious if anyone switched back or liked Reta better and the reasons.
