Susan i too have to take Zopi, i cut a 7.5mg tab in half and it stops night sweats flushes etc for up to 4hrs sometimes 5hrs, i have just had 2nights without tab and barely got 2hrs broken sleep due to body heat, sometimes it can take 15mins to cool off then 15mins to fall back to sleep then 10mins later, on comes the next lot of body heat so i am awake again..i feel so worn out...
My Gp last week had a chat with me about zopi, said maybe i could try 10mg Amitriptyline, to calm me down so i can drop off to sleep, but its not calming down i need to enable sleep, its the sweats i need to stop, had them now for 13yrs, been on Femseven 50 Hrt patches for 3yrs, and at 62, do not want to take any higher dose of Hrt, so like you i do not want to replace zopi with something else, i have tried cutting the tab into 4 which is difficult to do, and took just 1 bit of it, but that did not work so i know i need the 3.75mg to get 4hrs straight sleep, also my eye bags look worse after 2nts without sleep..tried 2 banana each day, but not working, tried hot drink, even tried small brandy, but still the hot sweats wake me..Can you please post if lowering your zopi works for you..xx
