Mine was so bad with my son I had to take a specific medine that they use in children for migraines. It lasted weeks at a time. But I hated to take it when I realized it was a class c drug. Tylenol and coke is what got me through the thang. I'm so sorry you have to deal with this. I hate headaches.
I get bad migraines and thankfully not with this pregnancy, but with my son they were sooo bad. Drink lots of water but also my doctor said I could drink one can of Coke a day and that really helped. Tylenol and one can a day. I don't even like Coke and I'm a Dr Pepper drinker when I drink soda. But it works the best. I drink it now when I feel a migraine coming on.
