Thanks for posting your query.
The symptoms you have described could be due to-
1. Generalized viral illness.
2. Improper diet.
3. Anaemia.
4. Electrolyte imbalance.
5. Hormonal disbalance like hypothyroidism.
5. Anxiety neurosis.
All these possibilities need to be ruled out after a proper physical examination and related blood tests.
Till the time you get evaluated for these possibilities, there are some of the other lifestyle options which you can follow:
1) You can take electrolyte XXXXXXX fluids like oralyte and fresh fruit juices for symptomatic relief. Taking a well balanced diet will be helpful.
2) Do not take caffeine or alcohol at night just before going to bed.
3) Indulge in yoga and meditation to calm your mind.
4) You can also indulge in progressive muscle relaxation which is useful in anxiety by alternately tensing and relaxing the muscles.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Dr. Praveen Tayal.

Dr. Thank you. I will request those tests.
But -- could these symptoms be due to an intolerance to wheat?
I ate bread in Spain with no problem although I avoided wheat
In Canada. Upon my return here I have been eating regular bread
Everyday. Symptoms seem worse after I eat.
Answered by Dr. Praveen Tayal 1 hour later
The symptoms you have could be related to wheat intolerance. You can avoid taking bread for a few days and see if the symptoms improve.
Best regards.
