Starting Letrazole after Exemestane

Hello,

 

iv been on Exemestane and Zolodex for 3months and have just stopped the Exemestane (oncologist recommended) and am starting letrazole (continuing with Zolodex) today as I was having very bad Headaches/Migraines and sickness every week.

 

Has anyone else switched from Exemestane to Letrazole or anyone that’s one Letrazole can you advise how this drug is compared to Exemestane? 

Any advice is greatly appreciated
