Hello Madam, I am sorry to read about your troubles!
Unfortunately, there is no non-prescription product that has been shown to be effective. Non-pharmacological measures are mostly recommended:
Try to figure out what might be triggering or making your symptoms worse:
What I suggest for the next 4 to 6 weeks is to keep a diary where you write down everything you consume as well as the quantities, but also the activities you undertake, and your state of mind (fatigue, stress, etc.). In the second column you could write down the occurrence and extent of the symptoms. We could then identify some possible causes. This may take several weeks so I suggest being diligent.
Certain foods can trigger hot flashes such as alcohol, coffee and spicy foods.
If you haven't already done so, I also suggest doing at least 30 minutes of moderate-intensity exercise a day, which can help reduce hot flashes
If this is not enough, you will need a thorough medical evaluation of your needs.
Tom Samaha, pharmacist
