Isn't it a lack of salt causing the problem? You sweat more in summer, hence the salt lack and the cramping in summer only.
When I went to India, my co-worker had had dreadful cramps on his previous visit - his leg ended up going black! The doctor told him to take 2 sachets of rehydration salts daily. This to me seemed excessive, but coworker was particularly sensitive to salt loss it seems. Rehydration satchets - and the powders you are searching for, are just sugar, flavoring and salt, I have a keyring measurer to mix my own in the (not yet happened) event I got a runny belly.
Myself, I just added salt to my daily juice, and was fine in the 45 degree heat of India.
Maybe try a salted juice before bedtime? Increase or decrease the salt as required.
